[PATCH v3 2/3] cxgb4: use module_long_probe_init()

From: Luis R. Rodriguez
Date: Tue Aug 12 2014 - 18:28:50 EST


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

cxgb4 probe can take up to over 1 minute when the firmware is
is written and installed on the device, even after this the device
driver still does some device probing and can take quite a bit.
This driver needs fixing but right now it simply wont' work on
some systems. Use 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.
