wil6210: prevent external wmi commands during suspend flow
In __wmi_send we check if fw is ready at the beginning of the function.
While we wait for the completion of the previous command, system suspend
can be invoked and reset the HW, causing __wmi_send to read from HW
registers while it is not ready.
Taking the wmi_mutex in the reset flow when setting the FW ready bit
to zero will prevent the above race condition.

ath9k: Simplify and fix eeprom endianness swapping
The three eeprom implementations had quite some duplicate code when it
came to endianness swapping.
Additionally there was a bug in eeprom_4k and eeprom_9287 which
prevented the endianness swapping from working correctly, because the
swapping code was guarded within an "if (!ath9k_hw_use_flash(ah))". In
eeprom_def this check did not exist, so it seems that eeprom_def was the
only implementation where endianness swapping worked.
This patch takes the duplicate code and moves it from eeprom_* to
eeprom.c. The new code is derived from eeprom_def, while taking into
account the specifics from the other implementations.

iwlwifi: mvm: ROC: Extend the ROC max delay duration & limit ROC duration
When associated to an AP and a ROC event with a long duration is scheduled
the FW may have a hard time scheduling a consecutive time event, since it
has to remain on the connection channel to hear the AP's DTIM.
In addition, when associated and a ROC is requested with a duration
greater than the DTIM interval, the FW will not be able to schedule
the ROC event, since it needs to wake up for the DTIM.
Increasing the "max delay" duration to the DTIM period will allow the FW to
wait until after the DTIM and then schedule the ROC time event.
Limiting the ROC to be less than the DTIM interval will assure that the
time event will be scheduled for at least part of the time (instead of
automatically failing)
Extend the ROC max delay duration to min(dtim_interval * 3, 600TU),
and limit the duration to be less than the DTIM interval.

brcmfmac: Disable runtime pm for USB.
Currently runtime pm is enabled for USB, but it is not properly
supported by driver. This patch disables the runtime PM support
completely for USB, as it currently can result in problems on
some systems.

brcmfmac: Remove unnecessary check from start_xmit.
The brcmf_netdev_start_xmit checks if the ndev is still valid by
checking if it still exists in database. This check is not needed
and therefor removed.

brcmfmac: Simplify and fix usage of brcmf_ifname.
brcmf_ifname is a debug function to return a name related to an ifp,
but is using a rather complex implementation. It was also used
wrongly from bcdc as it did not use the bsscfgidx as it was supposed
to, but bssidx. This patch fixes that bug and simplifies
brcmf_ifname.
