Subject: [PATCH 1/4] dmaengine: ep93xx_dma: Remove unneeded ERROR check before clk_put
Date: Mon, 16 May 2022 16:41:36 +0800	[thread overview]
Message-ID: <20220516084139.8864-2-wanjiabing@vivo.com> (raw)
In-Reply-To: <20220516084139.8864-1-wanjiabing@vivo.com>

clk_put() already uses !clk and IS_ERR(clk) to check ERROR or NULL.
Remove unneeded ERROR or NULL check for edmac->clk.
