Hi folks, Currently, when the device is removed (or the driver is unbound) the nouveau_drm structure de-allocated. However, it's still accessible from and used by some DRM layer callbacks. For example, file handles can be closed after the device has been removed (physically or otherwise). This series converts the Nouveau device structure to be allocated and de-allocated with the

The FBIOPUT_CON2FBMAP ioctl takes a console_lock(). When this is called while nouveau was runtime suspended, a deadlock would occur due to nouveau_fbcon_set_suspend also trying to obtain console_lock(). Fix this by delaying the drm_fb_helper_set_suspend call. Based on the i915 code (which was done for performance reasons though). Cc: Chris Wilson <chris at chris-wilson.co.uk> Cc: Daniel
