I guess that's a feeble attempt to compensate for the fact it's not a C
string. The string coming from the controller firmware appears to be a
fixed 16-byte length. And so is the inquiry buffer that it's being
copied to.

If the code would just use the inquiry string verbatim instead of
removing leading spaces and padding it. But there was probably some
crappy device out there that broke something for someone...

Anyway. Terminating the string is not the right fix.
