[alsa-devel] [PATCH] ASoC: xlnx: Use devm_platform_ioremap_resource() in xlnx_formatter_pcm_probe()

[Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Thu, 19 Sep 2019 17:27:57 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
