[PATCH] spi: xtensa-xtfpga: Use devm_platform_ioremap_resource() in xtfpga_spi_probe()

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sat, 21 Sep 2019 15:35:08 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
