      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

      Use 1UL for unsigned long, or we'll meet a overflow issue with UBSAN.

      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.
