Merge tag 'iio-for-3.9a' of... 

Merge tag 'iio-for-3.9a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan says:

	First round of IIO new stuff and cleanups for 3.9

	Here we have:
	* RTC driver for the hid-sensor hubs.  This is routed through here with
	  agreement of Jiri Kosina and Andrew Morton.
	* Some small patches doing dead code removal and fixing some comments.
	* max1363 - move to the triggered_buffer helpers (basically duplicate code
	  removal).
	* lp8788 - parent device change from the i2c device to the intermediate mfd.

	So the bulk of what we have is actually outside the IIO tree but the RTC
	driver in question is dependent on some patches that directly effect IIO so
	I am routing it through IIO with the agreement of the relevant maintainers
	(Andrew is acting as maintainer of RTC at the moment).  The majority of
	HID-sensor related code is in IIO and it now crosses 3 subsystems so it
	was going to be a bit awkward whatever route it took.
