The use of kmap() is being deprecated in favor of kmap_local_page() where
it is feasible. With kmap_local_page(), the mapping is per thread, CPU
local and not globally visible.
load_and_flush_by_kmap() is a function where the use of kmap_local_page()
in place of kmap() is correctly suited.
Convert load_and_flush_by_kmap() from kmap() to kmap_local_page().

Clang static analysis reports this representative issue
atomisp-ov2722.c:920:3: warning: 3rd function call
argument is an uninitialized value
dev_err(&client->dev, "sensor_id_high = 0x%x\n", high);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
high and low are only set when ov2722_read_reg() is successful.
Reporting the high value when there is an error is not
meaningful. The later read for low is not checked. high
and low are or-ed together and checked against a non zero
value.
Remove the unneeded error reporting for high. Initialize
high and low to 0 and use the id check to determine if
the reads were successful
The later read for revision is not checked. If it
fails the old high value will be used and the revision
will be misreported.
Since the revision is only reported and not checked or
stored it is not necessary to return if the read with
successful. This makes the ret variable unnecessary
so remove it.

These ioctls allow userspace to load custom programs into the ISP, which:
a) Seems dangerous
b) Cannot be used by opensource userspace since there is no FOSS code to
create such programs
b) These seem to be unused even by the Android closed source camera code
(they don't show up in a strace of the camera app)
So removing these seems be a good idea. Another reason to remove these is
that atomisp_acc_map() is the only user of the userptr functionality in
hmm_alloc(), so it gets in the way of further cleanups / simplification
of the hmm code.

Simplify the handling of "power sequences". At the moment, this is rather
complicated:
The hal layer calls HalPwrSeqCmdParsing. This function takes a pointer to
a power sequence. The sequences themselves are defined as global variables
in a separate file. There's an alias for each sequence, the callers of
HalPwrSeqCmdParsing use these aliases instead of the sequences themselves.
There's no point in passing the sequences around. We can move the
sequences into the same file as the HalPwrSeqCmdParsing function where
they are used. Callers of HalPwrSeqCmdParsing can refer to a sequence by
using a numeric define rather than a pointer to the sequence.

Also, send the connected links information to userspace.

In order to support multi-link operation with multiple links,
start adding some APIs. The notable addition here is to have
the link ID in a new nl80211 attribute, that will be used to
differentiate the links in many nl80211 operations.
So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID
attribute (as well as the NL80211_ATTR_MLO_LINKS attribute)
and plugs it through the system in some places, checking the
validity etc. along with other infrastructure needed for it.
For now, I've decided to include only the over-the-air link
ID in the API. I know we discussed that we eventually need to
have to have other ways of identifying a link, but for local
AP mode and auth/assoc commands as well as set_key etc. we'll
use the OTA ID.
Also included in this patch is some refactoring of the data
structures in struct wireless_dev, splitting for the first
time the data into type dependent pieces, to make reasoning
about these things easier.

On Hantro G2 decoder on IMX8MQ strides requirements aren't the same
for NV12_4L4 and NV12 pixel formats. The first one use a 4 bytes padding
while the last one needs 16 bytes.
To be sure to provide the correct stride in all cases we need:
- to relax the constraints on codec formats so set step_width to 4
- use capture queue format and not the output queue format when applying
the pixel format constraints.
- put the correct step_width constraints on each pixel format.
Move HEVC SPS validation in hantro_hevc.c to be able to perform it
when setting sps control and when starting to decode the bitstream.
Add a new test in HEVC SPS validation function to check if resolution
is still matching the hardware constraints.
With this SAODBLK_A_MainConcept_4 and SAODBLK_B_MainConcept_4 conformance
tests files are correctly decoded with both NV12 and NV12_4L4 pixel
formats. These two files have a resolution of 1016x760.
Add defines for the various used resolutions.
For other variants than Hantro G2 on IMX8M keep the same step_width to
avoid regressions.
Fluster HEVC test score is now 128/147 vs 126/147 with the both pixel
formats as decoder output.
Fluster VP9 test score stay at 147/303.

This replaces all of the dprintk macro calls with the zrdev_dbg,
zrdev_info, or zrdev_err calls as appropriate. This allows for the
removal of the dprintk macro from each file it is defined in, along with
the removal of module params that track the debugging level.
In the case that the debugging level was used in a comparison, this has
been replaced with checking the console level debugging and making a
decision from there. If the console debugging level is at least the
KERN_ debugging level equivalent, then the comparison will evaluate as
true.
There are a few instances where pr_debug must be used over the
zrdev_dbg. These occur in the module cleanup functions because there
should be no devices defined once we get here, so we don't have a device
to pass to zrdev_dbg.

2012, with commit db3b9e990e ("Staging: VME: move VME drivers out of
staging") stating:
The VME device drivers have not moved out yet due to some API
questions they are still working through, that should happen soon,
hopefully.
However, this never happened: maintenance of drivers/vme effectively
stopped in 2017, with all subsequent changes being treewide cleanups.
No hardware driver remains in staging, only the limited user-level
access, and I just removed one of the two bridge drivers and the only
remaining board.
drivers/staging/vme/devices/ was recently moved to
drivers/staging/vme_user/, but as the vme_user driver is the only one
remaining for this subsystem, it is easier to just move the remaining
three source files into this directory rather than keeping the original
hierarchy.

Since "struct dcon_priv" is per a device struct, I assume that
dcon_set_source_sync() needs to wait for only one work associated with
that device. Therefore, wait for only that work using flush_work().

The commit eecb3e4e5d ("staging: olpc_dcon: add OLPC display controller
(DCON) support") added this driver in 2010, and has been in staging since
then. It was marked as broken at some point because it didn't even build
but that got removed once the build issues were addressed.
But it seems that the work to move this driver out of staging has stalled,
the last non-trivial change to fix one of the items mentioned in its todo
file was commit e40219d5e4 ("staging: olpc_dcon: allow simultaneous XO-1
and XO-1.5 support") in 2019.
And even if work to destage the driver is resumed, the fbdev subsystem has
been deprecated for a long time and instead it should be ported to DRM.
Now this driver is preventing to land a kernel wide change, that makes the
num_registered_fb symbol to be private to the fbmem.c file.
So let's just mark the driver as broken. Someone can then work on making
it not depend on the num_registered_fb symbol, allowing to drop the broken
dependency again.

In _rtw_init_xmit_priv, we use the res variable to store the error
return from the newly converted rtw_alloc_hwxmits function. Sadly, the
calling function interprets res using _SUCCESS and _FAIL still, meaning
we change the semantics of the variable, even in the success case.
This leads to the following on boot:
r8188eu 1-2:1.0: _rtw_init_xmit_priv failed
In the long term, we should reverse these semantics, but for now, this
fixes the driver. Also, inside rtw_alloc_hwxmits remove the if blocks,
as HWXMIT_ENTRY is always 4.

gbaudio_dapm_free_controls() iterates over widgets using
list_for_each_entry_safe(), which leaves the loop cursor pointing to a
meaningless structure if it completes a traversal of the list. The
cursor was set to NULL at the end of the loop body, but would be
overwritten by the final loop cursor update.
Because of this behavior, the widget could be non-null after the loop
even if the widget wasn't found, and the cleanup logic would treat the
pointer as a valid widget to free.
To fix this, introduce a temporary variable to act as the loop cursor
and copy it to a variable that can be accessed after the loop finishes.
This was detected with the help of Coccinelle.

checkpatch.pl:
- that open brace { should be on the previous line
- else should follow close brace '}'
- braces {} are not necessary for single statement blocks

When issue_action_BA compiles an addba request, it does not add any
extensions. start_seq_num is the last field of the addba request.
The length of the request is the offset of the end of start_seq_num in the
struct ieee80211_mgmt that defines the message.
Use offsetofend to calculate this offset and drop the intermediate pktlen
increments as we add addba request components. (We have to keep the
increments for other message types until we use offsetofend for them as
well.)

Use the mgmt structure and defines from ieee80211.h to set the
capabilities field of an addba request.
If issue_action_BA is called with action == WLAN_ACTION_ADDBA_REQ, the
status parameter contains the tid.

Use the mgmt structure in issue_action_BA to set the action codes.
We have to distinguish between the different message types.
We also have to increment the packet length manually as we're no longer
calling rtw_set_fixed_ie, which increments the length.

Use the mgmt structure in issue_action_BA to set the category of the
outgoing frame. Remove the rtw_set_fixed_ie call.
We can now use the define directly, the category variable can be removed.
rtw_set_fixed_ie increments pattrib->pktlen, we have to do this ourselves
now (until we use a proper way to calculate the packet length).

Define a struct ieee80211_mgmt variable in issue_action_BA, this will make
it much simpler to populate the fields of the outoing frame.
Use the new mgmt variable to set the type and subtype of the frame.

Remove the unnecessary category check in issue_action_BA. category is
initialised to 3 (WLAN_CATEGORY_BACK) and never updated.
The rtw_set_fixed_ie call gets a pointer to category but it doesn't update
the value.
