Christophe noticed that a recent patch adding a missing clock disable to
one of the Qualcomm rpm driver error paths was broken. This would lead
to the provider not being registered on msm8996 which is the only
platform using this code path.

Turns out, however, that the power domain attach during probe is bogus
and would always succeed as any power domain would already have been
attached by the platform bus code.

Georgi, the offending commit is currently in your icc-next (and local
icc-fixes) branch. Perhaps you can fold in the fixup unless you prefer
applying it on top.

The bogus PM domain lookup is redundant and confusing but should
otherwise be benign so the removal could be applied to either branch.

Hi Johan,

Thank you for all the fixes!

Thanks Christophe for catching this!

Thanks Konrad for testing and confirming!

Maybe then I'll just drop this:
	interconnect: qcom: rpm: fix probe PM domain error handling
and apply this one instead:
	interconnect: qcom: rpm: drop bogus pm domain attach

BR,
Georgi

Sure, that works too. Wasn't sure whether you preferred incremental
fixes on top or not.

I've checked the end result in linux-next against my local branch and
everything looks good.

Thanks for getting that sorted.
