Subject: [PATCH v2 05/15] HID: logitech-hidpp: forward device info in power_supply

Better forwarding the device name, manufacturer and serial to upower.
Note that serial is still empty, it will be filled in a later patch
in this series.

Signed-off-by: Benjamin Tissoires <benjamin.tissoires@...hat.com>

changes in v2:
* model stripped of Logitech
* vendor Logitech -> Logitech, Inc.
* use hidpp->name for the power_supply name (so that it can be overloaded)
