[PATCH] net: ethernet: ti: cpsw: using pm_runtime_resume_and_get instead of pm_runtime_get_sync

From: cgel . zte
Date: Tue Apr 12 2022 - 05:37:36 EST


From: Minghao Chi <chi.minghao@xxxxxxxxxx>

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.
