sata_mv: remove unnecessary initialization
Tejun Heo [Mon, 10 May 2010 19:41:27 +0000 (21:41 +0200)]
sata_mv initializes unused ioports fields including bmdma_addr to
NULL.  As later changes will conditionalize BMDMA, this makes sata_mv
unnecessarily dependent on BMDMA.  Remove the unnecessary
initialization.
