[PATCH net-next 5/7] net: ipa: get rid of extra clock reference

From: Alex Elder
Date: Tue Aug 10 2021 - 15:27:35 EST


Suspending the IPA hardware is now managed by the runtime PM core
code. The ->runtime_idle callback returns a non-zero value, so it
will never suspend except when forced. As a result, there's no need
to take an extra "do not suspend" clock reference.
