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.
