Subject: [PATCH] drm/meson: Delete an error message in meson_dw_hdmi_bind()

From: Markus Elfring <elfring@...rs.sourceforge.net>

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.
