Presumably this was so we could redefine BEACON_LOST_COUNT_MIN, but it's fine to unused code. The define isn't needed at all, so you can delete that as well. regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
