From 5ff0dd18267efc0e7b0352fe54b74114b58535ae Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Sat, 20 Mar 2010 15:13:00 +0100 Subject: [PATCH] Staging: dream: fix dangling i2c pointers Fix I2C-drivers which missed setting clientdata to NULL before freeing the structure it points to. Also fix drivers which do this _after_ the structure was freed already.
