Subject: [PATCH] drm/bridge: it6505: Fix return value check for pm_runtime_get_sync
Date: Thu, 27 Oct 2022 11:21:49 +0800 [thread overview]
Message-ID: <20221027032149.2739912-1-treapking@chromium.org> (raw)
`pm_runtime_get_sync` may return 1 on success. Fix the `if` statement
here to make the code less confusing, even though additional calls to
`it6505_poweron` doesn't break anything when it's already powered.
This was reported by Dan Carpenter <dan.carpenter@oracle.com> in
https://lore.kernel.org/all/Y1fMCs6VnxbDcB41@kili/
Fixes: 10517777d302 ("drm/bridge: it6505: Adapt runtime power management framework")
