Subject: [PATCH 3/3] drm/gma500: Delete an unnecessary return statement in
 oaktrail_crtc_hdmi_dpms()

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

The script "checkpatch.pl" pointed information out like the following.

WARNING: void function return statements are not generally useful

Thus remove such a statement in the affected function.
