libata-pmp-prep: add @new_class to ata_dev_revalidate()
Consider newly found class code while revalidating. PMP resetting always results in valid class code and issuing PMP commands to ATA/ATAPI device isn't very attractive. Add @new_class to ata_dev_revalidate() and check class code for revalidation. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
