Subject: [PATCH] media: smiapp: Fix runtime PM imbalance on error
Date: Fri, 22 May 2020 17:03:13 +0800 [thread overview]
Message-ID: <20200522090313.10634-1-dinghao.liu@zju.edu.cn> (raw)
When v4l2_async_register_subdev_sensor_common() returns
an error code, a pairing runtime PM usage counter
decrement is needed to keep the counter balanced.
