[PATCH AUTOSEL 5.2 009/171] drm/bochs: Fix connector leak during driver unload
From: Sam Bobroff <sbobroff at linux.ibm.com>
[ Upstream commit 3c6b8625dde82600fd03ad1fcba223f1303ee535 ]
When unloading the bochs-drm 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_atomic_helper_shutdown() in
bochs_pci_remove().
Fixes: 6579c39594ae ("drm/bochs: atomic: switch planes to atomic, wire up
helpers.")
