Subject: USB: usbip: remove useless call in usbip_recv
Date: Tue, 2 Jan 2018 08:02:06 -0600 [thread overview]
Message-ID: <20180102140206.GA26171@embeddedor.com> (raw)
Calling msg_data_left(&msg) is only useful for its return value,
which in this particular case is ignored.
Fix this by removing such call.
Addresses-Coverity-ID: 1427080
Fixes: 90120d15f4c3 ("usbip: prevent leaking socket pointer address in messages")
