Subject[PATCH] dmaengine: owl: Use devm_platform_ioremap_resource() in owl_dma_probe()
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 22 Sep 2019 13:23:54 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
