Luis R. Rodriguez 25d3913181 firmware: provide helper for FW_OPT_USERHELPER
The macro FW_OPT_USERHELPER is only currently defined when
CONFIG_FW_LOADER_USER_HELPER is set. This is handled via an
ifdef around CONFIG_FW_LOADER_USER_HELPER. This makes reading
and understanding use FW_OPT_USERHELPER a bit convoluted.

Instead wrap the functionality implemented behind
CONFIG_FW_LOADER_USER_HELPER as we typically do in the
kernel.

Now when CONFIG_FW_LOADER_USER_HELPER is *not set*, then
simply the helper fw_sysfs_fallback() will not do anything.

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.
