Title
drm/vc4: Fix deadlock on DSI device attach error
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Fix deadlock on DSI device attach error DSI device attach to DSI host will be done with host device's lock held. Un-registering host in "device attach" error path (ex: probe retry) will result in deadlock with below call trace and non operational DSI display.
