The patchset generally looks OK, for my review comments please see separate
mails.  One thing I forgot to mention yet: please also fix DTS files so
exynos4_bus driver is finally functional (currently even with this patchset
it is not).

PS Please also add linux-samsung-soc@xxxxxxxxxxxxxxx to Cc: when sending
the next revision of this patchset.
