New Revision: 217537
URL: http://svn.freebsd.org/changeset/base/217537

Log:
  Remove bogus check.  pcib_get_bus() (like other BUS_ACCESSOR() methods)
  doesn't "fail", it may merely return garbage if it is not a valid ivar
  for a given device.  Our parent device must be a 'pcib' device, so we
  can just assume it implements pcib IVARs, and all pcib devices have a
  bus number.
