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
