Subject: [PATCH 1/2] fbdev/uvesafb: Remove uvesafb_exec() prototype from
 include/video/uvesafb.h
Date: Fri,  6 Oct 2023 17:43:46 -0300

uvesafb_exec() is a static function defined and called only in
drivers/video/fbdev/uvesafb.c, remove the prototype from
include/video/uvesafb.h.

Fixes the warning:
./include/video/uvesafb.h:112:12: warning: 'uvesafb_exec' declared 'static' but never defined [-Wunused-function]
when including '<video/uvesafb.h>' in an external program.
