Since mwifiex_ds_misc_subsc_evt is used in an asynchronous case,
store the structure in the long-lived mwifiex_private instead of
on the calling stack.
This fixes a problem where the response of the asynchronous
operation would corrupt a stack frame potentially in use by
a different thread.

clears boolean and waits for boolean to be set (by another

while result was already received. First clearing the flag and

The TX filter bit for a station would be set by the HW
when a frame is not acked. A frame would be completed with
ATH9K_TXERR_FILT status only when the corresponding filter bit
for the destination station is already set.
Currently, un-acknowledged packets are added to the pending queue
and retried, but the "clear_dest_mask" bit in the descriptor is
set only when the TX status has been ATH9K_TXERR_FILT. This results
in packet loss and the log shows:
wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746071
wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746076
wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746377
...
...
This issue can be resolved by making sure that the destination
mask is cleared when the packet is being retried and the earlier
TX status is ATH9K_TXERR_XRETRY.

It is not necessary to hold the firmware memory during the whole
driver lifetime, and obviously it does waste memory. Suppose there
are 4 ath9k-htc usb dongles working, kernel has to consume about
4*50KBytes RAM to cache firmware for all dongles. After applying the
patch, kernel only caches one single firmware image in RAM for
all ath9k-htc devices just during system suspend/resume cycle.
When system is ready for loading firmware, ath9k-htc can request
the loading from usersapce. During system resume, ath9k-htc still
can load the firmware which was cached in kernel memory before
system suspend.

items even when the tracepoint is disabled.
Instead, loop in the tracepoint assignment.
This reduces overhead if tracing is compiled
into the driver but not enabled and slightly
reduces overall driver size as well:

The brcmsmac driver requests firmware but doesn't document the
dependency. This means that software that analyzes the modules to
determine if firmware is needed won't detect it.
Specifically, (at least) openSUSE won't install the kernel-firmware
