@Philipp, do you have any comments on this?
From reading of the option help text, I feel the option is not recommended?
config FW_LOADER_USER_HELPER_FALLBACK
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.
