Subject: [PATCH] drm/sun4i: tcon: Delete an error message in
 sun4i_tcon_init_irq()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 5 Apr 2020 13:45:53 +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.
