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. Signed-off-by: Luis R.

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.
