commit ef3355759e8327193760dedf507598602432866c Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Thu Mar 19 21:04:23 2015 +0200
devicetree: Change scan_bus() prototype in device ops
The input/output value max is no longer used for tracking the bus enumeration sequence, everything is handled in the context of devicetree bus objects.
