Colin Ian King d8353a7500 staging: gdm724x: redundant variables idProduct and idVendor
Variable idProduct and idVendor are being assigned but are never used
hence they are redundant and can be removed.

Cleans up clang warnings:
warning: variable 'idProduct' set but not used [-Wunused-but-set-variable]
warning: variable 'idVendor' set but not used [-Wunused-but-set-variable]

Greg Kroah-Hartman ad9bd58c2a staging: gdm724x: remove redundant license information
Now that the SPDX tag is in all gdm724x files, that identifies the
license in a specific and legally-defined manner.  So the extra GPL text
wording can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

Greg Kroah-Hartman 1146ee4a9a staging: gdm724x: add SPDX identifiers to all files.
It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Fix up the all of the staging gdm724x files to have a proper SPDX
identifier, based on the license text in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of
the full boiler plate text.

Luc Van Oostenryck e71e17d3b6 staging: gdm724x: fix gdm_lte_tx()'s return type
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.

Fix this by returning 'netdev_tx_t' in this driver too.

Linus Torvalds 449fcf3ab0 Staging/IIO patches for 4.15-rc1
Here is the "big" staging and IIO driver update for 4.15-rc1.
 
 Lots and lots of little changes, almost all minor code cleanups as the
 Outreachy application process happened during this development cycle.
 Also happened was a lot of IIO driver activity, and the typec USB code
 moving out of staging to drivers/usb (same commits are in the USB tree
 on a persistent branch to not cause merge issues.)
 
 Overall, it's a wash, I think we added a few hundred more lines than
 removed, but really only a few thousand were modified at all.
 
 All of these have been in linux-next for a while.  There might be a
 merge issue with Al's vfs tree in the pi433 driver (take his changes,
 they are always better), and the media tree with some of the odd atomisp
 cleanups (take the media tree's version).

Greg Kroah-Hartman b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

Gargi Sharma c95d2e87fc staging: gdm724x: Replace ternary operator with min macro
Use macro min() to get the minimum of two values for
brevity and readability. The macro MUX_TX_MAX_SIZE
has a value of 2048 which is well within the integer
limits. This check was done manually.

Javier Rodriguez efe96779e5 staging: gdm724x: modify icmp6_checksum for returning a correct data type.
The icmp6_checksum was returning an invalid data type as the expected type
is __sum16. For returning such data type, icmp6_checksum, now, is using
the kernel functions for computing the checksum.

Here, the sparse message:

Dan Carpenter cd47e4d69a staging: gdm724x: fix a couple array overflows
The find_dev_index() function is frustrating.  If you give it an invalid
index then it returns 0.  That was the intent except there is an
off-by-one so it can return MAX_NIC_TYPE which is one higher than we
want.

There is one caller which had a sanity check to catch invalid returns,
but the other two callers assumed that index was valid.

My feeling is that when we are given invalid indexes, that should be
treated like an error and we abandon what we were doing.

Eric S. Stone 457c005aaf staging: gdm724x: update HCI structs with new bitwise types
Update the driver's HCI structs and associated endian-converter
functions with new driver-specific bitwise types. The new types
encourage correct endian-handling within the driver by triggering
sparse warnings when mixing with other types. The driver's
endian-converters provide correct and warning-free conversions.

Driver-specific bitwise types are used instead of the standard
endian-specific types because the attached device can be of either
endian. This is also why the driver has its own endian-conversion
functions, which consider endianness of both the cpu and the attached
device.

Introducing the new types to the converters fixes the sparse warnings:

With concurrency managed workqueues, use of dedicated workqueues
can be replaced by using system_wq. Drop usb_tx_wq and usb_rx_wq
by using system_wq.

Since there are multiple work items per udev but different udevs
do not need to be ordered, increase of concurrency level by
switching to system_wq should not break anything.

cancel_work_sync() is used to ensure that work is not pending or
executing on any CPU.

Lastly, since all devices are suspended, which shutdowns the work
items before the driver can be unregistered, it is guaranteed
that no work item is pending or executing by the time exit path
runs.
