[PATCH/RFT 0/3] ath10k: fixes

[Michal Kazior]

Hi,

This patchset addresses recently spotted issue
with (yet another) scheduling while atomic bug
(the other being WEP key index setting). This one
is related to hw_config() and powersave settings.
This comes from recent changes I've do to HTC/WMI.
WMI commands can now block so it's illegal to call
them in an atomic context anymore.

ath10k needs to setup some settings per-vdev (i.e.
per-interface) such as powersave, rts, fragmentation.
Until now mac80211 iteration functions were used.
However using non-atomic iteration function variant
doesn't solve the problem as it introduces an
issue with iflist_mtx deadlock in some cases.

I briefly tried to reproduce the issue Kalle
reported but was unsuccessful thus the "/RFT".
