As there aren't any sysfs entries that have those uppercase letters, I opted to teach the get_abi.pl script to threat such uppercase chars as wildcards. The same can't be done with N, because the USB subsystem (and a couple of other ABIs) use uppercase N as valid symbols like "bNum.*". Long term, one alternative would be to replace the What fields by a regular expressions on ABI. That would avoid some magic inside get_abi.pl. However, a change like that would require touching almost all files, and has a drawback to make them more obscure - even if we use named group regexes. Thanks, Mauro
