I would move the modification of the vsp1 driver to Javier's patch that
modifies the OMAP3 and OMAP4 drivers. Alternatively you could squash them into
this patch, but I believe having a first patch that adds the inline function
and a second patch that modifies all drivers to use it would be better.
