Subject: [PATCH AUTOSEL 5.4 294/350] spi: tegra20-slink: add missed clk_unprepare
Date: Tue, 10 Dec 2019 16:06:39 -0500 [thread overview]
Message-ID: <20191210210735.9077-255-sashal@kernel.org> (raw)
In-Reply-To: <20191210210735.9077-1-sashal@kernel.org>
From: Chuhong Yuan <hslester96@gmail.com>
[ Upstream commit 04358e40ba96d687c0811c21d9dede73f5244a98 ]
The driver misses calling clk_unprepare in probe failure and remove.
Add the calls to fix it.
