commit c061046fe9ce3ff31fb9a807144a2630ad349c17 upstream.
Currently, the battery timer is set up for all devices using hid-apple,
irrespective of whether they actually have a battery or not.
APPLE_RDESC_BATTERY is a quirk that indicates the device has a battery
and needs the battery timer. This patch checks for this quirk before
setting up the timer, ensuring that only devices with a battery will
have the timer set up.
Fixes: 6e143293e1 ("HID: apple: Report Magic Keyboard battery over USB")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
