This looks better, but there are still two minor issues:
You have one trailing whtespace error. Please the scripts/checkpatch.pl
script on the patch and correct the error.
The title of the commit message should indicate that this is an userspace
patch (this seems to be the convention that other patches have adhered
to). So:
'staging: usbip: userspace: <blah blah>'
not
'staging: usbip: <blah blah>;

As of Matt Mooney's major refactoring in 2011, usbip port
option was left out. Add support for this option in
a manner similar to the old implementation.
Sample output:
Imported USB devices
====================
Port 00: <Port in Use> at Full Speed(12Mbps)
unknown vendor : unknown product (1687:6211)
2-1 -> usbip://192.168.122.152:3240/1-1
-> remote bus/dev 001/002

Changes since v1:
* remove devid from the printed info
* arrange formatting a bit
* don't bail out when port file doesn't exist, just print whatever info
is available
* replace void cast with __attribute__((unused))
