Subject: [PATCH v4 79/79] media: hantro: do a PM resume earlier
Date: Wed, 28 Apr 2021 16:52:40 +0200
Message-ID: <569838d406dde80dcc64989a663882817a54cbb2.1619621413.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1619621413.git.mchehab+huawei@kernel.org>

The device_run() first enables the clock and then
tries to resume PM runtime, checking for errors.

Well, if for some reason the pm_runtime can not resume,
it would be better to detect it beforehand.

So, change the order inside device_run().
