From f322d5f0097333343bfd92b47258ee997c889263 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Sat, 20 Mar 2010 15:12:54 +0100 Subject: mfd: Fix dangling 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.
