Rob Herring 593bc4d008 drm/panfrost: Fix possible suspend in panfrost_remove
Calls to panfrost_device_fini() access the h/w, but we already done a
pm_runtime_put_sync_autosuspend() beforehand. This only works if the
autosuspend delay is long enough. A 0ms delay will hang the system when
removing the device. Fix this by moving the pm_runtime_put_sync_suspend()
after the panfrost_device_fini() call.
