USB: xhci: Refactor test for vendor-specific completion codes.
All commands that can be issued to the xHCI hardware can come back with vendor-specific "informational" completion codes. These are to be treated like a successful completion code. Refactor out the code to test for the range of these codes and print debugging messages. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
