@Philipp, do you have any comments on this?

From reading of the option help text, I feel the option is not


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.
