Subject: [PATCH] qemu-nbd: Fix a memleak in nbd_client_thread()
Date: Tue, 1 Dec 2020 06:13:49 +0000	[thread overview]
Message-ID: <20201201061349.110262-1-alex.chen@huawei.com> (raw)

When the qio_channel_socket_connect_sync() fails
we should goto 'out_socket' label to free the 'sioc' instead of
goto 'out' label.
In addition, now the 'out' label is useless, delete it.
