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

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.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!
