Subject: [PATCH AUTOSEL 4.9 28/34] drm/ast: Fix connector leak during driver unload
From: Sam Bobroff <sbobroff@...ux.ibm.com>
[ Upstream commit e594a5e349ddbfdaca1951bb3f8d72f3f1660d73 ]
When unloading the ast driver, a warning message is printed by
drm_mode_config_cleanup() because a reference is still held to one of
the drm_connector structs.
Correct this by calling drm_crtc_force_disable_all() in
ast_fbdev_destroy().
