Tiny nit, if you happen to respin this, "default n" is always the
default, so there's never a need to specify it.

How does this match up with the MODULE_FIRMWARE() aliases that end up in
a kernel module so that the tools know to add the firmware to the system
in the proper place (i.e. initramfs or something like that)?

I always thought you needed to individually list the firmware files, or
does the rust implementation now somehow handle that in a programatic
way from strings like this?

thanks,
