[PATCH] Relax idecd dma alignment check
Only the address needs alignment of mask bits, length should work with
a relaxed alignment check.
Signed-off-by: Jens Axboe <axboe@suse.de>
[ This is take 2: make the length check be for 16-byte alignment, not
just word alignment. That should hopefully keep everybody happy,
while still allowing CD writing with DMA ]
