Merge branch 'omap-fixes-urgent' of git://git.linaro.org/people/rmk/linux-arm
This pull request covers the major oopsing issues with OMAP, caused by
the lack of the TWL driver. Even when the TWL driver is not built in,
we shouldn't oops.
* 'omap-fixes-urgent' of git://git.linaro.org/people/rmk/linux-arm:
ARM: omap: fix broken twl-core dependencies and ifdefs
ARM: omap: fix oops in drivers/video/omap2/dss/dpi.c
ARM: omap: fix oops in arch/arm/mach-omap2/vp.c when pmic is not found
