[ Upstream commitf4abaa9eeb] The power supply states of discharging, charging, full, etc, represent state of charging, not the capacity level of the battery (for which we have a separate property). Current HID usage tables to not allow for expressing charging state of the batteries found in generic styli, so we should simply assume that the battery is discharging even if current capacity is at 100% when battery strength reporting is done via HID interface. In fact, we were doing just that before commit581c448476. This change helps UIs to not mis-represent fully charged batteries in styli as being charging/topping-off.

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.
