http://perforce.freebsd.org/chv.cgi?CH=54331 Change 54331 by scottl@scottl-esp-sparc64 on 2004/06/07 18:14:37 CAM does not track timeouts itself, it just provides a timeout hint for drivers to use for doing their own tracking. Adjust the use of the callout API for this. Also fix up ncr53c9x_select().
