The function prism2sta_ev_txexc() is called by the function
hfa384x_usbin_txcompl() to print the transmit exception event - a debug

The debugging utility function can be called directly by

Checkpatch suggests the use of strscpy() instead of strncpy().
The advantages are that it always adds a NUL terminator and it prevents
a read overflow if the src string is not properly terminated. One
potential disadvantage is that it doesn't zero pad the string like
strncpy() does.
In this code, strscpy() and strncpy() are equivalent and it does not
affect runtime behavior. The string is zeroed on the line before
using memset(). The resulting string was always NUL terminated and
PRISM2_USB_FWFILE is string literal "prism2_ru.fw" so it's NUL
terminated.
However, even though using strscpy() does not fix any bugs, it's
still nicer and makes checkpatch happy.

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device. (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)
Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown". After a timer is set to this state, then it can no
longer be re-armed.
The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed. It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.
This was created by using a coccinelle script and the following
commands:
$ cat timer.cocci
@@
expression ptr, slab;
identifier timer, rfield;
@@
(
- del_timer(&ptr->timer);
+ timer_shutdown(&ptr->timer);

del_singleshot_timer_sync() used to be an optimization for deleting timers
which are not rearmed from the timer callback function.
This optimization turned out to be broken and got mapped to
del_timer_sync() about 17 years ago.

Add support for the drivers to indicate the information of links used

Also, send the connected links information to userspace.
Add a netlink flag attribute to indicate that userspace supports
handling of MLO connection. Drivers must not do MLO connection when this

Tasklets have long been deprecated as being too heavy on the system
by running in irq context - and this is not a performance critical
path. If a higher priority process wants to run, it must wait for
the tasklet to finish before doing so.
The completion_bh tasklet will now run in process context and have
further concurrency (tasklets being serialized among themselves),
but this is done holding the ctlxq.lock, so it should be fine.

The comment explains that short circuiting here is undesirable, as the
calls to test_and_{clear,set}_bit() need to happen for both sides of the
expression.
Clang's suggestion would work to silence the warning but the readability
of the expression would suffer even more. To clean up the warning and
make the block more readable, use a variable for each side of the
bitwise expression.

Here is the big set of staging and IIO driver updates for 5.15-rc1.
Also included in here are the counter driver subsystem updates as the
IIO drivers needed them.
Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
driver and replaced it with a newer version of the driver that had been
maintained out-of-tree by Larry with the end goal of actually being able
to get this driver out of staging eventually. Despite that driver being
"newer" the line count of this pull request is going up.
Some drivers moved out of staging as well, which is always nice to see,
that is why there are additions to the mfc and misc driver subsystems.
All of these were acked by the various subsystem maintainers involved.
But by far, as normal, it's coding style cleanups all over the
drivers/staging/ tree in here.
Full details of these changes are in the shortlog.
All of these have been in linux-next for a while with no reported

Merge tag 'staging-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull IIO and staging driver updates from Greg KH:
"Here is the big set of staging and IIO driver updates for 5.15-rc1.
Also included in here are the counter driver subsystem updates as the
IIO drivers needed them.
Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
driver and replaced it with a newer version of the driver that had
been maintained out-of-tree by Larry with the end goal of actually
being able to get this driver out of staging eventually. Despite that
driver being "newer" the line count of this pull request is going up.
Some drivers moved out of staging as well, which is always nice to
see, that is why there are additions to the mfc and misc driver
subsystems. All of these were acked by the various subsystem
maintainers involved.
But by far, as normal, it's coding style cleanups all over the
drivers/staging/ tree in here.
Full details of these changes are in the shortlog.
All of these have been in linux-next for a while with no reported
problems"
[ Note: the r8188eu merge clashed with commit 89939e8906 ("staging:
rtlwifi: use siocdevprivate") from the networking tree. When resolving
the issue, I noted that the whole r8188eu rtw_android code is dead
since commit ae7471cae0 ("staging: r8188eu: remove rtw_ioctl
function").
End result: the merge resolution was to throw all of that away,
rather than do the mindless fixup to code that isn't actually
reachable - Linus ]

There is no need for the a3/a4 union. The two structs are identical
except for the addition of a4. Excepting one place, the structs are
only ever used in the union, and the union is always allocated at full
size. The one instance of the a3-specific struct can be replaced with
the full version, as no sizing information is used. Replace the union
with the a4 version of the struct. "diffoscope" reports there are no
object code differences after this change.

struct hfa384x_wpa_data ends with a flexible array, but it is allocated
on the stack. This means it can never hold any data. Disable the
memcpy() calls in and out of the structure, since it must always be
zero. This could never have worked.

wlan-ng has two private ioctls that correctly work in compat
mode. Move these over to the new ndo_siocdevprivate mechanism.
The p80211netdev_ethtool() function is commented out and
has no use here, so this can be removed

strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. The safe replacement is strscpy().

Currently p80211knetdev_do_ioctl use type casting to req->data to prevent
sparse warning while calling memdup_user, instead of type casting it here,
its better to change data type for data inside p80211ioctl_req to include
__user.
