[PATCH] libata: clear only affected flags during ata_dev_configure() ata_dev_configure() should not clear dynamic device flags determined elsewhere. Lower eight bits are reserved for feature flags, define ATA_DFLAG_CFG_MASK and clear only those bits before configuring device. Without this patch, ATA_DFLAG_PIO gets turned off during revalidation making PIO mode unuseable. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
