[PATCH v3 3/3] mptsas: use module_long_probe_init()

From: Luis R. Rodriguez
Date: Tue Aug 12 2014 - 18:28:56 EST


From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>

Its reported that mptsas can at times take over 30 seconds
to recognize SCSI storage devices [0], this is done on the
driver's probe path. Use the the new module_long_probe_init()
to annotate this driver's probe is broken and require some love,
but makes the driver operational until that is fixed.
