Subject: [PATCH] media: platform: sti: hva: Fix runtime PM imbalance on error
Date: Thu, 21 May 2020 18:05:02 +0800 [thread overview]
Message-ID: <20200521100503.13454-1-dinghao.liu@zju.edu.cn> (raw)
pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced.
