Subject: [PATCH] gpu/drm: ingenic: Delete an error message in
 ingenic_drm_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 5 Apr 2020 11:25:30 +0200

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

This issue was detected by using the Coccinelle software.
