Chris Wilson 409fab53ed drm: Return ENODEV if the inode mapping changes ... commit da58405860 upstream. Replace a BUG_ON with an error code in the event that the inode mapping changes between calls to drm_open. This may happen for instance if udev is loaded subsequent to the original opening of the device: [ 644.291870] kernel BUG at drivers/gpu/drm/drm_fops.c:146!
