Dear all,

linux 5.3.1

Thinkpad X260
iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208
iwlwifi 0000:04:00.0: loaded firmware version 36.8fd77bb3.0 op_mode iwlmvm
since about 5.3.0 I get a lot of warnings in the syslog about iwlmvm.
It starts with

This repeats a few times (2-4) and then it settles down.
WIFI works without any problems, though.

This made me check my logs. It turns out that in my current v5.3.1 session
(now in its fifth day) there are 128 of these warnings. In my case the warning
also mentions
drivers/net/wireless/intel/iwlwifi/mvm/scan.c:1874
My previous session (v5.3.0) accumulated 162 of these warnings in about six
days, while the session before that (v5.2.y) showed none.
Just like in Norbert's case, wifi appears to work fine.

I'm guessing this should fix it:

Yes, I can confirm that with this patch added on top of 5.3.1 I don't
see the warnings anymore.
Thanks a lot
