Lukas Wunner 523872f6b0 drm/nouveau: Turn off CRTCs on driver unload ... nouveau leaks a runtime pm ref if at least one CRTC is enabled on unload. The ref is taken by nouveau_crtc_set_config() and held as long as a CRTC is in use. nv04_display_destroy() should solve this by turning off all CRTCs, but (1) nv50_display_destroy() doesn't do the same and (2) it's broken since commit d6bf2f3707 ("drm/nouveau: run mode_config destructor before destroying internal display state") because the crtc structs are torn down by drm_mode_config_cleanup() before being turned off. Also, there's no locking. Move the code to turn off all CRTCs from nv04_display_destroy() to nouveau_display_destroy() so that it's called for both nv04 and nv50 and before drm_mode_config_cleanup(). Use drm_crtc_force_disable_all() helper to save on code and have proper locking.
