Hi Jiri!

Patch 1 contains multiple fixes, mainly use of sleeping calls in atomic contexts:
I'd say slap it in 7.1 fixes.

Patch 2 is a minor improvement removing an OOM message to align the driver
to newer code where that would have been a flagged warning: probably a fix for
7.1 but there's no rush for this one.

Patch 3 is a logic fix, condition is very rare (not sure if even possible) but belongs
to 7.1 almost certainly.

Patch 4 new feature support: goes to 7.2.

Patch 5 unsure. It adds support to the backlight, but to properly do it I'll need
to wait for lamparray to be merged since autonomous mode must be disabled
to take effect. I'd say 7.2 just because of the missing lamparray. Merging in 7.1
has no downsides, yet IDK if putting in 7.1 violates some rule (probably yes?).

Please give a (very) quick read to the following link:
https://github.com/OpenGamingCollective/asusctl/issues/119#issuecomment-4723566635

This is something I am full of tickets for, probably we have reached the thousand
between discord, github and gitlab: very prominent issue and I'm eagerly waiting
for lamparray support to appear upstream.

Thanks,
Denis
