From: Greg KH
Date: Tue Feb 15 2011 - 20:57:35 EST


2.6.32-longterm review patch. If anyone has any objections, please let us 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.
