[PATCH] [71/275] pata_mpc52xx: inherit from ata_bmdma_port_ops

From: Andi Kleen
Date: Wed Mar 30 2011 - 17:58:08 EST


2.6.35-longterm review patch. If anyone has any objections, please let me know.

------------------
From: Tejun Heo <tj@xxxxxxxxxx>

commit 77c5fd19075d299fe820bb59bb21b0b113676e20 upstream.

pata_mpc52xx supports BMDMA but inherits ata_sff_port_ops which
triggers BUG_ON() when a DMA command is issued. Fix it.
