The recent series for OPP/pmdomains [1] that has been queued for v6.12 via the
pmdomain tree introduces a regression for the Qcom Venus driver, which was
reported to me offlist.

This small series attempts to fix the problem by making the assignment of the
required-devs more robust and correct. More details are available in the commit
messages.

I have tested this on specific test setup with Qemu, trying to model all the
various way required-opps are being used. I would appreciate help with further
test on HW and reviews, of course!

Kind regards
Ulf Hansson
