[ Upstream commit 037c1aaeb96fe5f778026f4c1ef28b26cf600bfa ] The XP-PEN Deco LW drawing tablet can be connected by USB cable or using a USB Bluetooth dongle. When it is connected using the dongle, there might be a small delay until the tablet is paired with the dongle. Fetching the device battery during this delay results in random battery percentage values. Add a quirk to avoid actively querying the battery percentage and wait for the device to report it on its own.

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.
