Clean some code that became obfuscated over the years:

Don't keep duplicate files in the files list just to
mark the device as "known" later.  XXX: Since the
device list isn't unique (there can be two "device foo"
directives, as this the case with LINT+DEFAULTS), we
have to traverse it all to mark all copies of the same
device as "used", but this is not worse than it was.
