Subject: [PATCH -next] hwrng: atmel - use clk_disable_unprepare instead of clk_disable
Date: Fri, 11 Nov 2016 14:56:47 +0000	[thread overview]
Message-ID: <1478876207-29820-1-git-send-email-weiyj.lk@gmail.com> (raw)

From: Wei Yongjun <weiyongjun1@huawei.com>

Since clk_prepare_enable() is used to get trng->clk, we should
use clk_disable_unprepare() to release it for the error path.
