Merge tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux
Pull GPIO changes from Grant Likely:
"The usual selection of bug fixes and driver updates for GPIO. Nothing
really stands out except the addition of the GRGPIO driver and some
enhacements to ACPI support"
I'm pulling this despite the earlier mess. Let's hope it compiles these
days.
