[PATCH] libata: let ATA_FLAG_PIO_POLLING use polling pio for ATA_PROT_NODATA
Even if ATA_FLAG_PIO_POLLING is set, libata uses irq pio for the ATA_PROT_NODATA protocol. This patch let ATA_FLAG_PIO_POLLING use polling pio for the ATA_PROT_NODATA protocol. Signed-off-by: Albert Lee <albertcc@tw.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
