[PATCH] spi: mediatek: Use devm_platform_ioremap_resource() in mtk_spi_probe()

[Markus Elfring <Markus.Elfring@xxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 21 Sep 2019 14:45:40 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
