Subject: [PATCH 2/4] gui: graphic_utils: Stub out fb_* functions
Date: Mon,  5 Feb 2018 09:29:33 -0800	[thread overview]
Message-ID: <20180205172935.25232-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180205172935.25232-1-andrew.smirnov@gmail.com>

Stub out fb_* functions so as to avoid having to #ifdef the code using
them.
