Such loops can cause unnecessary delays if the
CONFIG_FW_LOADER_USER_HELPER is enabled.
Since it is not possible to use vendor's firmware partition as is (you
have to either bind-mount a subdir or use a plenty of symlinks) one
might as well symlink .mbn to .mdt file.
Another option is to explicitly specify something like `firmware-name
= "./adsp.mdt";'

But yes, this whole series is a balance of pros and cons, as it was
discussed last week.
