[PATCH] USB: prevent catch-all USB aliases in modules.alias
visor.c defines one empty slot in USB ids table that can be filled in at
runtime using module parameters. file2alias generates catch-all alias for it:
alias usb:v*p*dl*dh*dc*dsc*dp*ic*isc*ip* visor
patch adds the same sanity check as in depmod to scripts/file2alias.
