Subject: [PATCH 4.9 54/61] drm/ast: Fix connector leak during driver unload
Date: Thu, 20 Dec 2018 10:18:54 +0100 [thread overview]
Message-ID: <20181220085845.944338047@linuxfoundation.org> (raw)
In-Reply-To: <20181220085843.743900603@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
[ 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().
