[PATCH] drm/exynos: Delete an error message in three functions

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sun, 5 Apr 2020 14:10:09 +0200

The function “platform_get_irq” can log an error already.
Thus omit redundant messages for the exception handling in the
calling functions.

This issue was detected by using the Coccinelle software.
