From 1c51361a9867021dd7444b56d87834003d4ca67d Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 19 Oct 2007 00:30:10 +0200 Subject: ide: add IDE_HFLAG_SERIALIZE host flag Add IDE_HFLAG_SERIALIZE host flag to tell ide_pci_setup_ports() to set hwif/mate->serialized and convert aec62xx, cs5530 and sc1200 host drivers to use it.
