[PATCH] drm/tegra: vic: Use devm_platform_ioremap_resource() in vic_probe()

[Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sat, 21 Sep 2019 20:51:52 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
