[PATCH v3 02/14] soc: mediatek: mtk-svs: Use pm_runtime_resume_and_get() in svs_init01()
From: Roger Lu
Date: Tue Jan 03 2023 - 06:30:05 EST
From: Shang XiaoJing <shangxiaojing@xxxxxxxxxx>
svs_init01() calls pm_runtime_get_sync() and added fail path as
svs_init01_finish to put usage_counter. However, pm_runtime_get_sync()
will increment usage_counter even it failed. Fix it by replacing it with
pm_runtime_resume_and_get() to keep usage counter balanced.
