Subject: [PATCH] ASoC: xlnx: Use devm_platform_ioremap_resource() in xlnx_formatter_pcm_probe()
Date: Thu, 19 Sep 2019 17:38:04 +0200 [thread overview]
Message-ID: <8f7cf483-6ab3-d00f-5606-863e9f5b31fc@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.
