Subject: [PATCH v2 RFT] media: exynos4-is: add missed clk_disable_unprepare in remove
Date: Thu, 19 Dec 2019 15:48:24 +0800 [thread overview]
Message-ID: <20191219074824.15047-1-hslester96@gmail.com> (raw)
This driver forgets to disable and unprepare clock when remove.
Add a call to clk_disable_unprepare() to fix it.
Signed-off-by: Chuhong Yuan <hslester96@gmail.com>

Changes in v2:
- Add a check of pm_runtime_enable() to match enable in probe.
- Add RFT tag.
