Subject: [PATCH 4.9 28/42] net/qla3xxx: fix an error code in ql_adapter_up()
Date: Mon, 13 Dec 2021 10:30:10 +0100	[thread overview]
Message-ID: <20211213092927.487719816@linuxfoundation.org> (raw)
In-Reply-To: <20211213092926.578829548@linuxfoundation.org>

From: Dan Carpenter <dan.carpenter@oracle.com>

commit d17b9737c2bc09b4ac6caf469826e5a7ce3ffab7 upstream.

The ql_wait_for_drvr_lock() fails and returns false, then this
function should return an error code instead of returning success.

The other problem is that the success path prints an error message
netdev_err(ndev, "Releasing driver lock\n");  Delete that and
re-order the code a little to make it more clear.
