[Qemu-devel] [PATCH 8/8] usb-linux: fix /proc/bus/usb/devices scan

[Gerd Hoffmann <kraxel@redhat.com>]

Commit 0c402e5abb8c2755390eee864b43a98280fc2453 is incomplete
and misses one of the two function pointer calls in
usb_host_scan_dev().  Add the additional port handling logic
to the other call too.

Spotted by Coverity.
