Lucas Stach 11c63e5740 firmware: add nowarn variant of request_firmware_nowait()
Device drivers with optional firmware may still want to use the
asynchronous firmware loading interface. To avoid printing a
warning into the kernel log when the optional firmware is
absent, add a nowarn variant of this interface.

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.
