Subject: [PATCH] media: vsp1: Fix runtime PM imbalance in vsp1_probe
Date: Sat, 23 May 2020 19:54:26 +0800
Message-ID: <> (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.
