Merge tag 'iio-fixes-3.6b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

IIO fixes for elements queued for 3.6 merge window.

3 types of fix here.

1) Incorrect pointer casting via phys_addr_t which causes
   trouble on some architectures.
2) request_irq and free_irq dev_id parameters not matching.
3) Inconsistencies in client_data for some i2c devices
(writing one pointer and expecting another later).
