Author: mav Date: Sun Jul 18 07:13:55 2010 New Revision: 210205 URL: http://svn.freebsd.org/changeset/base/210205 Log: MFC r209884: If ata_sata_phy_reset() failed and ata_generic_reset() is not called, mark channel as having no devices connected. This improves hot-unplug operation on legacy-emulating SATA controllers.
