Accept "default" written to sysfs trigger attr. If the text "default" is written to the LED's sysfs 'trigger' attr, then call led_trigger_set_default() to set the LED to its default trigger. If the default trigger is set to "none", then led_trigger_set_default() will remove a trigger. This is in contrast to the default trigger being unset, in which case led_trigger_set_default() does nothing.

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 reStructuredText 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.
