ide: ide_timing_compute() fixup
XFER_SW_DMA_0 mode should be excluded from the extended cycle timing computations. [ This is just a documentation fix -- code inside the affected 'if' block already makes sure to accept only PIO modes. ] Noticed-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: David S.
