Subject: [PATCH] media: vpif: Fix runtime PM imbalance in vpif_probe
Date: Sat, 23 May 2020 19:49:17 +0800
Message-ID: <20200523114917.18222-1-dinghao.liu@zju.edu.cn> (raw)

When platform_get_resource() returns an error code, a
pairing runtime PM usage counter decrement is needed
to keep the counter balanced.
