   4 Subject: ARM: davinci: PM: Do not free useful resources in normal path in 'davinci_pm_init'

   8 commit 95d7c1f18bf8ac03b0fc48eac1f1b11f867765b8 upstream.
   9
  10 It is wrong to iounmap resources in the normal path of davinci_pm_init()
  11
  12 The 3 ioremap'ed fields of 'pm_config' can be accessed later on in other
  13 functions, so we should return 'success' instead of unrolling everything.
