Subject: video: Avoid using #ifdef in video blitting code
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=46421197d51df7f050e9b0bdcd3edd0df3eaaf35;p=u-boot.git

video: Avoid using #ifdef in video blitting code

This code does not really need to use #ifdef. We can use if() instead and
gain build coverage without impacting code size.

Change the #ifdefs to use IS_ENABLED() instead.
