Patch 1 prevents gpiolib from accessing GPIOs that haven't been
properly requested.

Patch 2 adds an infrastructure for sparse GPIO maps

Patch 3 updates pinctrl-msm to use that expose that new infrastructure

Patch 4 updates pinctrl-qdf2xxx to work with the new feature in pinctrl-msm

Ok. What path doesn't request the gpio though? If we don't have a
path that fails to request the gpio before using it then I don't
see the need for this patch.

Sorry, I don't understand your question.  Patches 2-4 are all about 
creating a sparse GPIO map.  All patch 1 does is stop initializing all 
the GPIOs with an initial direction.
