      drm/udl: implement usb_driver suspend/resume. · 737ba109
      Haixia Shi authored
      The usb_driver suspend and resume function pointers must be populated
      to prevent forced unbinding of USB interface driver. See usb/core/driver.c:
      unbind_no_pm_drivers_interfaces().
      
      Restore mode and damage the entire frame buffer upon resume.
      
      TEST=suspend and resume with the same UDL device connected
      TEST=suspend with UDL, unplug UDL and resume
      TEST=suspend with UDL, unplug and connect another UDL device then resume

      drm/atomic: Reject properties not part of the object. · 4e9951d9
      Maarten Lankhorst authored
      The legacy setprop ioctl doesn't attempt to set properties
      that are not enumerated on the object. The atomic ioctl does,
      fix this by validating first.

      drm: drm_probe_helper: Fix output_poll_work scheduling · 339fd362
      Peter Ujfalusi authored
      drm_kms_helper_poll_enable_locked() should check if we have delayed event
      pending and if we have, schedule the work to run without delay.
      
      Currently the output_poll_work is only scheduled if any of the connectors
      have DRM_CONNECTOR_POLL_CONNECT or DRM_CONNECTOR_POLL_DISCONNECT with
      DRM_OUTPUT_POLL_PERIOD delay. It does not matter if we have delayed event
      already registered to be handled. The detection will be delayd by
      DRM_OUTPUT_POLL_PERIOD in any case.
      Furthermore if none of the connectors are marked as POLL_CONNECT or
      POLL_DISCONNECT because all connectors are either POLL_HPD or they are
      always connected: the output_poll_work will not run at all even if we
      have delayed event marked.
      
      When none of the connectors require polling, their initial status change
      from unknown to connected/disconnected is not going to be handled until
      the first kms application starts or if we have fb console enabled.
      
      Note that in general the output poll work should be enabled already
      when this happens, but at driver load usually the first probe happens
      before the output polling is enabled. This patch fixes this case.

      [danvet: Note when exactly this is an issue, since the probe code
      schedules the poll work itself already.]
