Woops, thanks for catching the misplaced '(' :) Actually the SCSI
identifiers on my laptops are not long enough to show the problem.

As for the whitespace, you don't need to trim it, that's actually why
strncmp() is used for the string comparison later on. SCSI strings
have always been whitespace-padded.

Actually, removing the trailing \n added by sysfs would be nice for
display purpose, but more than that is just wasting CPU cycles :)
