| |
Hi,
A minor slip up on my behalf broke ide-dma compile in 2.5.4-pre2 due to the scatterlist ->address removal. This patch should make it work again, but please not that it is NOT a good example for follow for folks trying to fixup other drivers due to address breakage...
scatterlist building for a task file ioctl will be moved to be unified with regular bio sglist building instead of the current nasty hack soonish.
