svn commit: r260086 - head/sys/dev/iwn

[Marius Strobl]

Author: marius
Date: Mon Dec 30 16:46:50 2013
New Revision: 260086
URL: http://svnweb.freebsd.org/changeset/base/260086

Log:
  - Probe with BUS_PROBE_DEFAULT instead of 0.
  - Remove clearing PCIM_CMD_INTxDIS; pci(4) will do that as appropriate since
    r189367.
