From d5185c4eb3a022f7e7a435238c2b0b885e6b4821 Mon Sep 17 00:00:00 2001 From: Damian Hobson-Garcia Date: Fri, 16 Nov 2012 14:46:12 +0900 Subject: [PATCH] drivers: uio: Only allocate new private data when probing device tree node 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. Reported-by: Fengguang Wu Signed-off-by: Damian Hobson-Garcia Cc: "Hans J.
