Hello,
Because I used gmail mobile app to response and the app decided that
always using HTML is a valid choice for every one, my previous mail
rejected by mailing lists.
Because of that I am (re)sending this mail. You can find contents of my
previous mail below.

Hi Roman,
Unfortunately I don't have XPS 13 and tested the patch on Dell Vostro
5481 and this patch is the result of bisection on Vostro.
At first, the Archlinux bug report I shared looked similar thus that
bug report contains lots of dmesg outputs from different users. But
yes probably there is 2 distinct issue which should be solved separately.
I will update commit message accordingly as soon as possible.
Regards,
Mehmet Akif

Since this bug report is about the Dell XPS 13 2-in1: I tested your
revert with this device, but the issue persists at least on this
device. So these might be two different issues, one for your device
and another one for the XPS.
