Today the non-essential pv devices are hard coded in the xenbus driver
and this list is lacking multiple entries.

This series reworks the detection logic of non-essential devices by
adding a flag for that purpose to struct xenbus_driver.

Juergen Gross (5):
  xen: add "not_essential" flag to struct xenbus_driver
  xen: flag xen_drm_front to be not essential for system boot
  xen: flag hvc_xen to be not essential for system boot
  xen: flag pvcalls-front to be not essential for system boot
  xen: flag xen_snd_front to be not essential for system boot
