[SCSI] mpt fusion: make logging a global sysfs parameter
Wire up the mpt_debug_level module parameter so you can write to the /sys/module/mptbase/parameters/mpt_debug_level and have it take effect in every ioc. Acked-by: "Moore, Eric" <Eric.Moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
