[PATCH 0/4] iommu: Small fixes and cleanups

[Joerg Roedel]

Hi,

here are a couple of iommu fixes and cleanups to fix compile
errors and some warnings on ARM and PPC.

Regards,

	Joerg

Joerg Roedel (4):
  iommu: Make more drivers depend on COMPILE_TEST
  iommu/exynos: Make driver depend on REGULATOR
  iommu/omap: Print phys_addr_t using %pa
  iommu/fsl: Use %pa to print phys_addr_t

[PATCH 2/4] iommu/exynos: Make driver depend on REGULATOR

[Joerg Roedel]

From: Joerg Roedel <jroedel-l3A5Bk7waGM@public.gmane.org>

When regulator is not selected during kconfig, linking of
the exynos iommu driver fails due to missing symbols.
Fix it!

Frankly, I never observed such issue. Could you provide the .config for 
such case? I know that existing exynos iommu driver is broken, but 
please, don't break it even more...

Removed this patch from my tree, as the issue was somewhere else.

Somewhere around line 1124 there another opportunity for this fix:
