[PATCH 00/11] i2c: rcar: cleanup series

[Wolfram Sang <wsa@the-dreams.de>]

Here are some patches to let the rcar driver have a diet without losing
functionality. IMO the code becomes more readable, too, although mileages may
vary about this or that change. Bus-free handling is improved, too. Tested with
renesas-devel-v3.15-rc7-20140526 on a Lager and Koelsch board. The git tree can
be found here, including one proof-of-concept enablement patch:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/rcar-cleanup

Please test, review, comment.

Thanks,

   Wolfram
