The qmi_wwan merge was trivial.

The caif_hsi.c, on the other hand, was not.  It's a conflict between
1c385f1fdf ("caif-hsi: Replace platform
device with ops structure.") in the net-next tree and commit
39abbaef19 ("caif-hsi: Postpone init of
HIS until open()") in the net tree.

I did my best with that one and will ask Sjur to check it out.

Johannes Berg eac9ac6d1f iwlwifi: fix activating inactive stations
When authentication/association timed out, the driver would
complain bitterly, printing the message
ACTIVATE a non DRIVER active station id ... addr ...

The cause turns out to be that when the AP station is added
but we don't associate, the IWL_STA_UCODE_INPROGRESS is set
but never cleared. This then causes iwl_restore_stations()
to attempt to resend it because it uses the flag internally
and uploads even if it didn't set it itself.

To fix this issue and not upload the station again when it
has already been removed by mac80211, clear the flag after
adding it in case we add it only for association.

Johannes Berg e75dac921d iwlwifi: limit mac_change_interface to BSS context
Currently when mac80211 asks to change the interface
type, we will accept it for both the BSS and PAN
contexts. This is not terribly complicated today,
but with the addition of the P2P Device abstraction
the PAN context handling will get more complex, so
restrict mac_change_interface to the BSS context.

Also fix a small locking issue and use is_active
instead of the vif pointer to check if the other
context is activated, guarding exclusive interface
types on the BSS context (IBSS) against the PAN
context being used for something else.

Johannes Berg e9c03d18c4 iwlwifi: increase scan timeout
When the first interface is active, then scanning
on it or the second interface can take a little
longer than 7s (I observed around 8s.) Bump the
timeout to 15s to avoid aborting a scan that is
still running, just taking more time.

Johannes Berg 3f8a9e7667 iwlwifi: fix radio reset scan dwell vs. quiet time
My previous commit to shorten the radio reset time
caused issues as the firmware checks the active
dwell time against the quiet time, asserting that
the dwell is >= quiet time. This isn't really
needed in case of passive scanning like here, but
of course we need to pass that check.

To fix this, override the quiet time to be the
same as the radio reset dwell time.

When debugging is disabled, the event log functions aren't
functional in the way that the debugfs file expects. This
leads to the debugfs access crashing. Since the event log
functions aren't functional then, remove the debugfs file

Johannes Berg 0d4e07726e iwlwifi: use minimal time for radio reset scan
The effect of using a short single-channel scan
to reset the radio is that scanning a channel
that isn't in use needs to re-tune the radio.
This means that the dwell time is irrelevant,
so use a shorter time.

While at it, clean up the code for this a bit.

Johannes Berg 601968b3bb iwlwifi: delay ROC if doing internal reset scan
When the device is doing an internal radio reset
scan, ROC can be rejected to the supplicant with
busy status which confuses it.

One option would be to queue the ROC and handle
it later, but since the radio reset scan is very
quick we can just wait for it to finish instead.

Also add a warning since we shouldn't run into
the case of having a scan active when requesting
a ROC in any other case since mac80211 will not
scan while ROC or ROC while scanning.

When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.

This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.
The message is the log that was printed is:

Queue 2 stuck for 10000ms

This doesn't seem to fix the higher queues that get stuck
from time to time.
