Hi Dave & Daniel,

Tvrtko is out today, so sending the -rc3 -fixes PR on behalf of him (picked and CI tested by Tvtko).

Major items are fix for GitLab #4698 (Dell DA310 Type-C dock issue) and engine busyness inconsitent value/timeout fixes when running with GuC.

Then two fixes for error paths and a smatch detected divide by zero fix.

Regards, Joonas
