Subject: [Qemu-devel] [PATCH 2/3] usb-host: Drop superfluous null test from usb_host_auto_scan()
Date: Thu, 10 Jan 2013 14:33:24 +0100 [thread overview]
Message-ID: <1357824805-31574-3-git-send-email-armbru@redhat.com> (raw)
In-Reply-To: <1357824805-31574-1-git-send-email-armbru@redhat.com>
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.
