Merge commit 'e257d969f36503b8eb1240f32653a1afb3109f86' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next

I think last commits in tag iwlwifi-next-for-kalle-2021-08-26 are not
ready yet so I'm skipping those and pulling an earlier commit. I
modified Luca's description below to not include the skipped commits.
