Subject: [PATCH] drm/etnaviv: Add missing pm_runtime_put
Date: Tue, 18 Jan 2022 06:16:31 -0800	[thread overview]
Message-ID: <1642515391-19329-1-git-send-email-lyz_cs@pku.edu.cn> (raw)

pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code, thus a matching decrement is needed
on the error handling path to keep the counter balanced.
