This is a patch set inspired by the recent patch Kai-Heng posted about the HD-audio mic-mute LED control. Currently HD-audio driver deals with the mute and mic-mute LED in several different ways: primarily with the direct callback of vmaster hook and capture sync hook, while another with the LED class device binding. The latter has been used for binding with the platform device LEDs like Thinkpad, Dell, Huawei. And, yet, recently we added our own LED classdev for the mic-mute LED on some HP systems although they are controlled directly with the callback; it's exposed, however, for the DMIC that is governed by a different ASoC driver. This patch set is an attempt to sort out and make them consistent: namely, * All LEDs are now controlled via LED class device * The generic driver provides helper functions to easily build up the LED class dev and the relevant mixer controls * Conversion of the existing framework and clean ups The patches are lightly tested in my side with a couple of machines and also through hda-emu tests. Some devices receive new kcontrols for the mute LED behavior (that have been missing so far), but anything else look good though my tests.

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.
