Subject: ihs_video_out: Fix error handling
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=6df07d854b9ee81d31fafcd83724bed7fb1fd6d7;p=u-boot.git

ihs_video_out: Fix error handling

The ihs_video_out driver's error handling is incorrect in two places
(one is a missing negation, and in one place a error should be ignored).

Fix these two instances.
