Subject: [PATCH v5 12/16] media: mtk-vcodec: Use pm_runtime_resume_and_get for PM get_sync
Date:   Sat, 10 Apr 2021 17:11:24 +0800

pm_runtime_get_sync will increment pm usage counter even it failed.
This patch use pm_runtime_resume_and_get instead of
pm_runtime_get_sync to keep usage counter balanced.
