Subject: [PATCH] ide-timings: use ->pio_mode value to determine fastest PIO speed
Use the current PIO mode value instead of the physical maximum one
to determine the fastest allowed PIO for shared PIO/DMA timings.
Affected host drivers: amd74xx and via82cxxx.
Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx>
