d1a55841ab net: Remove dev_err() usage after platform_get_irq()
We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

// <smpl>

expression ret;
struct platform_device *E;

ret =

platform_get_irq_byname(E, ...)

-dev_err(...);

5d29050b40 mac80211_hwsim: Extended Key ID API update
Prepare hwsim Extended Key ID support for a mac80211 API change.

The mac80211 flag IEEE80211_HW_EXT_KEY_ID_NATIVE is being replaced by
NL80211_EXT_FEATURE_EXT_KEY_ID which only must be set by drivers when
they support HW crypto.

This reverts commit cfe7007a9b ("mac80211_hwsim: Extended Key ID support").

49175fe63e iwlwifi: dvm: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  This driver was saving the debugfs file away to be
removed at a later time.  However, the 80211 core would delete the whole
directory that the debugfs files are created in, after it asks the
driver to do the deletion, so just rely on the 80211 core to do all of
the cleanup for us, making us not need to keep a pointer to the dentries
around at all.

This cleans up the structure of the driver data a bit and makes the code
a tiny bit smaller.

41a531ffa4 rt2x00usb: fix rx queue hang
Since commit ed194d1367 ("usb: core: remove local_irq_save() around
 ->complete() handler") the handler rt2x00usb_interrupt_rxdone() is
not running with interrupts disabled anymore. So this completion handler
is not guaranteed to run completely before workqueue processing starts
for the same queue entry.
Be sure to set all other flags in the entry correctly before marking
this entry ready for workqueue processing. This way we cannot miss error
conditions that need to be signalled from the completion handler to the
worker thread.
Note that rt2x00usb_work_rxdone() processes all available entries, not
only such for which queue_work() was called.

This patch is similar to what commit df71c9cfce ("rt2x00: fix order
of entry flags modification") did for TX processing.

This fixes a regression on a RT5370 based wifi stick in AP mode, which
suddenly stopped data transmission after some period of heavy load. Also
stopping the hanging hostapd resulted in the error message "ieee80211
phy0: rt2x00queue_flush_queue: Warning - Queue 14 failed to flush".
Other operation modes are probably affected as well, this just was
the used testcase.

ff414f31ce ath10k: work around uninitialized vht_pfr variable

cc0e5f1ce0 scripts/spelling.txt: drop "sepc" from the misspelling list
The RISC-V architecture has a register named the "Supervisor Exception
Program Counter", or "sepc".  This abbreviation triggers checkpatch.pl's
misspelling detector, resulting in noise in the checkpatch output.  The
risk that this noise could cause more useful warnings to be missed seems
to outweigh the harm of an occasional misspelling of "spec".  Thus drop
the "sepc" entry from the misspelling list.

3b57a10ca1 iwlwifi: pcie: don't service an interrupt that was masked
Sometimes the register status can include interrupts that
were masked. We can, for example, get the RF-Kill bit set
in the interrupt status register although this interrupt
was masked. Then if we get the ALIVE interrupt (for example)
that was not masked, we need to *not* service the RF-Kill
interrupt.
Fix this in the MSI-X interrupt handler.

ed3e4c6d3c iwlwifi: fix RF-Kill interrupt while FW load for gen2 devices
Newest devices have a new firmware load mechanism. This
mechanism is called the context info. It means that the
driver doesn't need to load the sections of the firmware.
The driver rather prepares a place in DRAM, with pointers
to the relevant sections of the firmware, and the firmware
loads itself.
At the end of the process, the firmware sends the ALIVE
interrupt. This is different from the previous scheme in
which the driver expected the FH_TX interrupt after each
section being transferred over the DMA.

In order to support this new flow, we enabled all the
interrupts. This broke the assumption that we have in the
code that the RF-Kill interrupt can't interrupt the firmware
load flow.

Change the context info flow to enable only the ALIVE
interrupt, and re-enable all the other interrupts only
after the firmware is alive. Then, we won't see the RF-Kill
interrupt until then. Getting the RF-Kill interrupt while
loading the firmware made us kill the firmware while it is
loading and we ended up dumping garbage instead of the firmware
state.

Re-enable the ALIVE | RX interrupts from the ISR when we
get the ALIVE interrupt to be able to get the RX interrupt
that comes immediately afterwards for the ALIVE
notification. This is needed for non MSI-X only.

ec46ae3024 iwlwifi: pcie: fix ALIVE interrupt handling for gen2 devices w/o MSI-X
We added code to restock the buffer upon ALIVE interrupt
when MSI-X is disabled. This was added as part of the context
info code. This code was added only if the ISR debug level
is set which is very unlikely to be related.
Move this code to run even when the ISR debug level is not
set.

Note that gen2 devices work with MSI-X in most cases so that
this path is seldom used.

c56e00a3fe iwlwifi: mvm: delay GTK setting in FW in AP mode
In AP (and IBSS) mode, we can only set GTKs to firmware after we have
sent down the multicast station, but this we can only do after we've
enabled beaconing, etc.

However, during rfkill exit, hostapd will configure the keys before
starting the AP, and cfg80211/mac80211 accept it happily.

On earlier devices, this didn't bother us as GTK TX wasn't really
handled in firmware, we just put the key material into the TX cmd
and thus it only mattered when we actually transmitted a frame.

On newer devices, however, the firmware needs to track all of this
and that doesn't work if we add the key before the (multicast) sta
it belongs to.

To fix this, keep a list of keys to add during AP enable, and call
the function there.
