Subject: [PATCH 2/3] cxgb4: ask for deferred probe

From: "Luis R. Rodriguez" <mcgrof@...e.com>

cxgb4 probe can take up to over 1 minute when the firmware is
is written and installed on the device. Use the new delayed probe
preference so that cxgb4 gets probed on the deferred workqueue.
Without this devices that require the update on firmware will fail
on probe.
