[PATCH 0/4] usb: dwc2: fix host mode external vbus supply management

[Amelie Delaunay]

This patchset fixes and improves host mode external vbus supply management,
mainly around suspend/resume use cases. It also avoid 'vbus regulator"
to be requested lots of times upon each call to dwc2_vbus_supply_init(),
especially when pm runtime is enabled.

  usb: dwc2: get optional vbus-supply regulator once
  usb: dwc2: fix a race with external vbus supply
  usb: dwc2: fix call to vbus supply exit routine, call it unlocked
  usb: dwc2: fix unbalanced use of external vbus-supply
