Ren Jianing ba8203c1b8 usb: gadget: u_audio: add uevent for ppm compensation 
This patch add uevent to notify the application layer how much ppm
is different between USB clk and AUDIO clk.

The event include two parts USB_STATE and PPM. For example:

  g_audio_work: sent uac uevent USB_STATE=SET_AUDIO_CLK PPM=12
  g_audio_work: sent uac uevent USB_STATE=SET_AUDIO_CLK PPM=-1

Note: The ppm compensation depends on the method implement of
clk drift and compensation in the rockchip_pdm.c driver. So if
you want the ppm compensation to take effect, please make sure
the commit "ASoC: rockchip: pdm: Add support for clk compensation"
is merged.

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.
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
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
