José Expósito 430786612a HID: input: report battery status changes immediately 
[ Upstream commit e94536e1d1 ]

Previously, the battery status (charging/discharging) was not reported
immediately to user-space. 

For most input devices, this wasn't problematic because changing their
battery status requires connecting them to a different bus.
For example, a gamepad would report a discharging status while
connected via Bluetooth and a charging status while connected via USB.

However, certain devices are not connected or disconnected when their
battery status changes. For example, a phone battery changes its status
without connecting or disconnecting it.
In these cases, the battery status was not reported immediately to user
space.

Report battery status changes immediately to user space to support
these kinds of devices.

README 

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.
