Changes v7:
- Remove the 'devm_pm_runtime_enable' change.

Above is the tag you ask. You are right, the 'devm_pm_runtime_enable'
tag I mentionded in the patchset v6 is truly a fake tag. So please
ignore this tag. What I intended to explain here was that I decided not
to use 'devm_pm_runtime_enable' to replace 'pm_runtime_enable'
functions. Unfortunately, the fake tag didn't explain this clearly in
the changelog, which was my fault. To address this, I updated patchset
v8 to include an explanation.

In patchset v6, I replaced 'pm_runtime_enable' with
'devm_pm_runtime_enable'. However, in patchset v8, I reverted this
change and included the reason for this decision in the changelog.
Apologize for the delay and the trouble again.
