   5     USB: add RESET_RESUME for webcams shown to be quirky
   6
   7     The new runtime PM code has shown that many webcams suffer
   8     from a race condition that may crash them upon resume.
   9     Runtime PM is especially prone to show the problem because
  10     it retains power to the cameras at all times. However
  11     system suspension may also crash the devices and retain
  12     power to the devices.
  13     The only way to solve this problem without races is in
  14     usbcore with the RESET_RESUME quirk.
