[PATCH 4/4] drivers: uio: Only allocate new private data when probing device tree node
From: Damian Hobson-Garcia
Date: Fri Nov 16 2012 - 00:47:12 EST
The same condition should be used both when allocating and freeing the
driver private data. When dev.of_node is non NULL, allocate a new
private data structure, otherwise use the values from the platform data.
