Dell laptops have another LED for mic-mute in addition to the master mute. The former is tied with the capture switch (in a reverse way) while the latter is tied with the master playback switch. We already have an enum control to change the behavior for the master mute LED in different ways, e.g. keeping always off or turning off at mute. But, the mic-mute LED has no such management but its behavior is hard-coded. This patch implements an enum control to change the mic-mute LED behavior like what we have for the master mute LED. The ctl provides four modes: keep-on, keep-off, follow-capture and follow-mute. The default mode is the last one, follow-mute, which follows the capture mute, i.e. LED turning on when the capture is off, and turning off when the capture is active.

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