Subject: [PATCH 6/13] ide: add IDE_HFLAG_SERIALIZE host flag
Date: Wed, 5 Sep 2007 23:53:28 +0200	[thread overview]
Message-ID: <200709052353.28577.bzolnier@gmail.com> (raw)


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.
