Comment # 1 on bug 1209980 from Takashi Iwai

It's already supported on Leap 15.5.  Backporting to Leap 15.4 is too difficult
due to kABI compatibility.

Note that ath11k driver has a known problem for the hibernation even in the
upsteram code.  It may lead to a kernel panic.  There is a workaround with a
systmd hook (bsc#1207948).
