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

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sat, 21 Sep 2019 15:12:33 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
