[ Upstream commit aa74f0687cfe998e59b20d6454f45e8aa4403c45 ]
1. When unsetting a mode, num_connector should be set to zero 2. The pixel_format field needs to be initialized as newer DRM internal functions checks this field 3. Take the drm_modeset_lock_all() because vmw_fb_kms_detach() can change current mode
