Subject: [PATCH] dmaengine: mediatek: Use devm_platform_ioremap_resource() in mtk_uart_apdma_probe()
Date: Sun, 22 Sep 2019 13:14:11 +0200 [thread overview]
Message-ID: <366e776c-8760-eeb7-c248-7380c9f4fd34@web.de> (raw)
From: Markus Elfring <elfring@users.sourceforge.net>

Simplify this function implementation by using a known wrapper function.
This issue was detected by using the Coccinelle software.
