[PATCH 2/3] firmware: qcom_scm: Always return devm_clk_get_optional errors

From: Konrad Dybcio
Date: Fri Jun 23 2023 - 17:50:48 EST


If devm_clk_get_optional throws an error, something is really wrong.
It may be a probe deferral, or it may be a problem with the clock
provider.

Regardless of what it may be, it should definitely not be ignored.
Stop doing that.
