Avoid assigning an IS_ERR value to the cm_id pointer. This fixes a few anomalies in the error flow due to confusion about checking for NULL vs IS_ERR, and eliminates the need to test for the IS_ERR value every time we wish to determine if the cma_id object has a cm device associated with it. Also, eliminate the now-unnecessary procedure cma_has_cm_dev (we can check directly for the existence of the device pointer -- for a non-NULL check, makes no difference if it is the iwarp or the ib pointer). Finally, make a few code changes here to improve coding consistency. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <roland@purestorage.com> |
