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.
