From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Object drm_mode is allocated by the call to drm_mode_find_dmt
(via the call to drm_mode_duplicate and drm_mode_create). The
object is never free'd and hence causes a small memory leak.
Fix this by kfree'ing drm_mode once it is no longer required.
Addresses-Coverity: ("Resource leak")
Fixes: 1d42bbc8f7f9 ("drm/fbdev: fix cloning on fbcon")
