Comment # 5 on bug 1180985 from Takashi Iwai

If the problem was seen on the early 5.10.x, it's possibly the bug of iwlwifi. 
This has been addressed on 5.10.4.  So you don't need that workaround.

OTOH, the 5.10.4 kernel got another bug about HDMI and this might lead to
another problem.  It was already fixed on the later kernel (5.10.5 should be
fine).
But if you want the workaround to be sure, just pass
  snd_hda_codec_hdmi.enable_silent_stream=0
as boot option.  The relevant bugs are bug 1180543 and bug 1180563.
