Subject: [PATCH 2/4] dmaengine: sprd-dma: Remove unneeded ERROR check before clk_disable_unprepare
Date: Mon, 16 May 2022 16:41:37 +0800	[thread overview]
Message-ID: <20220516084139.8864-3-wanjiabing@vivo.com> (raw)
In-Reply-To: <20220516084139.8864-1-wanjiabing@vivo.com>

clk_disable_unprepare() already checks ERROR by using IS_ERR_OR_NULL.
Remove unneeded ERROR check for sdev->ashb_clk.
