Subject: [PATCH 0/4] platform: arm64: thinkpad-t14s-ec: fixes and suspend
 support

I have a two fixes for the T14s Gen6 Snapdragon EC driver as well as
improved system suspend support. I've been using my Thinkpad with these
patches for a few weeks as daily driver doing regular system suspend and
things seem to run well.

If there is enough time after review the fixes are probably good
material for the 6.18 release cycle.
