Fallback user-helper invocation for firmware loading

configname: CONFIG_FW_LOADER_USER_HELPER_FALLBACK

Linux Kernel Configuration
└─>Device Drivers
└─>Generic Driver Options
└─>Fallback user-helper invocation for firmware loading
In linux kernel since version 3.17 (release Date: 2014-10-05)  
This option enables / disables the invocation of user-helper
(e.g. udev) for loading firmware files as a fallback after the
direct file loading in kernel fails. The user-mode helper is
no longer required unless you have a special firmware file that
resides in a non-standard path. Moreover, the udev support has
been deprecated upstream.

If you are unsure about this, say N here.
