Thinh Nguyen e591d7ca6e usb: gadget: composite: Inform controller driver of self-powered
commit 5e5caf4fa8d3039140b4548b6ab23dd17fce9b2c upstream.

Different configuration/condition may draw different power. Inform the
controller driver of the change so it can respond properly (e.g.
GET_STATUS request). This fixes an issue with setting MaxPower from
configfs. The composite driver doesn't check this value when setting
self-powered.

============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
