USB: serial: keyspan: handle unbound ports
[ Upstream commit 3018dd3fa114b13261e9599ddb5656ef97a1fa17 ]
Check for NULL port data in the control URB completion handlers to avoid
dereferencing a NULL pointer in the unlikely case where a port device
isn't bound to a driver (e.g. after an allocation failure on port
probe()).
Fixes: 0ca1268e109a ("USB Serial Keyspan: add support for USA-49WG & USA-28XG")
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
