svn commit: r185741 - head/sys/dev/pccbb

New Revision: 185741
URL: http://svn.freebsd.org/changeset/base/185741

Log:
  Use '0' rather than PZERO to not change the priority that I'm waiting
  at.  I don't think this will make a huge difference, but I have
  received a report of a interrupt storm on one 16-bit card that this
  might fix (chances are it won't, since I think that we may need to
  check both the CBB registers for the 16-bit card as well as the PCIC
  registers for power state change).
