[PATCH openEuler-1.0-LTS] drm: bridge/panel: Cleanup connector on bridge detach

From: Paul Cercueil <paul(a)crapouillou.net> stable inclusion from stable-v5.10.37 commit ce450934a00cf896e648fde08d0bd1426653d7a2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I94VOL CVE: CVE-2021-47063 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4d906839d321c2efbf3fed4bc31ffd9ff55b75c0 upstream. If we don't call drm_connector_cleanup() manually in panel_bridge_detach(), the connector will be cleaned up with the other DRM objects in the call to drm_mode_config_cleanup(). However, since our drm_connector is devm-allocated, by the time drm_mode_config_cleanup() will be called, our connector will be long gone. Therefore, the connector must be cleaned up when the bridge is detached to avoid use-after-free conditions. v2: Cleanup connector only if it was created v3: Add FIXME v4: (Use connector->dev) directly in if() block Fixes: 13dfc0540a57 ("drm/bridge: Refactor out the panel wrapper from the lvds-encoder bridge.")

If 'vmbus_establish_gpadl()' fails, the (recv|send)_gpadl will not be updated and 'hv_uio_cleanup()' in the error handling path will not be able to free the corresponding buffer. In such a case, we need to free the buffer explicitly.
