Merge tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6 

GPIO fixes for v3.3-rc2

Straight forward bug fixes in this branch.  A couple of x86 gpio drivers
missing spinlock initialization, an API change fixup for the samsung driver
and a name typo fix.

* tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6:
  gpio: Add missing spin_lock_init in gpio-ml-ioh driver
  gpio: Add missing spin_lock_init in gpio-pch driver
  gpio: samsung: adapt to changes in gpio specifier translator function declaration
  Correct bad gpio naming
