Commit8a2fa38fdd
removed the mode_fixup because it was empty, but652353e6e5
modified it to call drm_mode_set_crtcinfo() instead. Both commits are correct, but the merge of the two kept the nonempty version without the reference to it, as shown by the gcc warning: drm/sti/sti_crtc.c:54:13: error: 'sti_crtc_mode_fixup' defined but not used This restores the callback pointer to fix the merge. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reverts:8a2fa38fdd
("drm/sti: removed optional dummy crtc mode_fixup function.") Fixes:652353e6e5
("drm/sti: set CRTC modesetting parameters") Fixes:cf481068cd
