[PATCH v2 0/5] HID: add battery driver for the UNCTRL RAGE Wireless Mouse

This patchset adds battery reporting for the UNCTRL RAGE Wireless Mouse.
Parts of the driver are inspired by the Kysona HID driver
(drivers/hid/hid-kysona.c).

It was tested on an UNCTRL RAGE Wireless Mouse.

Changes in v2:
- restructure the battery handover to fix the races found in review
- register the replacement supply before the previous owner is torn down,
  so a failed registration cannot leave the mouse batteryless
- deliver the probe-time query reply with hid_device_io_start()
- schedule the polling on the freezable workqueue, no CPU wake during
  suspend
