[PATCH] greybus: using pm_runtime_resume_and_get to simplify the code

[cgel.zte]

From: Minghao Chi <chi.minghao@zte.com.cn>

Using pm_runtime_resume_and_get() to replace pm_runtime_get_sync and
pm_runtime_put_noidle. This change is just to simplify the code, no
actual functional changes.

Why are you sending patches from a random non-personal gmail address?

And why is this here?

NAK.

Greybus is using the pm_runtime_get_sync() consistently and mixing it up
with the new helper that uses a different naming scheme is just
confusing.

Use the new helper for your own code if you prefer, but there's really
no need to go around submitting this automatic conversions for code
that's already in the tree.
