[PATCH] media: rc: Use devm_platform_ioremap_resource() in tango_ir_probe()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 18 Sep 2019 12:30:18 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
