Subject: net/qla3xxx: fix an error code in ql_adapter_up()
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
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.
