Title:
  Bluetooth device Power percentage always shows 0%.

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  SRU Justification:

  Impact: Indicator UI shows 0% of batter of the bluetooth keyboard.
  This is because upower gets -ENODATA from the sysfs node, such as
  /sys/class/power_supply/hid-08\:b7\:38\:00\:09\:55-battery/capacity. 

  Fix: An upstream patch added the .raw_request operation in struct hid_ll_driver
  and made it assigned to the correct function in hidp.c

  Test case: I tested on my Lenovo Thinkpad X240 and an HP K4000 Bluetooth keyboard.
  Gerald Yang tested on an HP ProBook 450 G2/2248 and a Lenovo bluetooth keyboard.
  Both shows the bug is fixed by the patch.

  
  Frank Praznik (1):
    HID: Add the transport-driver functions to the HIDP driver.
