[Qemu-devel] [PATCH 2/3] usb-host: Drop superfluous null test from usb_host_auto_scan()

[Markus Armbruster]

Coverity points out that port is later passed to usb_host_open(),
which dereferences it.  It actually can't be null: it always points to
usb_host_scan()'s auto port[].  Drop the superfluous port == NULL
test.
