Hello,

> this is the 2nd version of this series whose goal is to make struct
> of_device_id.data const. Conceptually a driver must not modify the data
> contained there so making it const is the right thing.

I rebased my branch at:

	git://git.pengutronix.de/git/ukl/linux.git ofdeviceiddata

on top of v3.6-rc1 and retested the arm and powerpc defconfigs and a
powerpc allyesconfig. The result is still the same, i.e. a new warning
in drivers/regulator/twl-regulator.c because the probe routine modifies
the of_match table.

The series was contained in next up to next-20120725 (as commit

	100e8f5 (Merge branch 'ofdeviceiddata' of git://git.pengutronix.de/git/ukl/linux into late/warnings)

with an encoding error in the commit log btw). Don't know why it was
dropped from next. (late/warnings didn't show up in next-20120725's
arch/arm/arm-soc-for-next-contents.txt, maybe that's the reason?)

Compared to v2 of the series this drops two patches that made it in
during the v3.6 merge window.

The following changes since commit 0d7614f09c1ebdbaa1599a5aba7593f147bf96ee:
