Author: jhb Date: Mon Oct 15 16:09:59 2012 New Revision: 241591 URL: http://svn.freebsd.org/changeset/base/241591 Log: Add locking to the aic(4) driver and mark it MPSAFE. - Move 'free_scbs' into the softc rather than having it be a global list and convert it to an SLIST instead of a hand-rolled linked-list. - Use device_printf() and device_get_unit() instead of storing the unit number in the softc. - Remove use of explicit bus space handles and tags. - Don't call device_set_desc() in the pccard attach routine, instead set a default description during the pccard probe if the matching product doesn't have a name.
