Some cards (like mvsas) have issue troubles if non-NCQ commands are mixed with NCQ ones. Fix this by using the libata default NCQ check routine which waits until all NCQ commands are complete before issuing a non-NCQ one. The impact to cards (like aic94xx) which don't need this logic should be minimal Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman --- Reading git-diff-tree failed
