8e7d967244 staging: iio: remove specific chrdev for event reading. Get fd from ioctl on buffer.
Change suggested by Arnd Bergmann.

No real reason to have two chrdevs per device. This step merges them into one.
Currently this means that events will only work on devices with buffers. THat will
be remedied shortly.

V2: set name for event attribute groups.  Otherwise they all sorts of fun occurs on
dynamic channel event attribute creation.

99c978529a staging: Add module.h to drivers/staging users
Lots of people expect module.h to just "be there" without
any #include effort.  But we are crushing that.  So fix those
files in staging relying on implicit module.h presence.

c4b14d99bb staging:iio:events: use IIO_<TYPE> and IIO_MOD_<> instead of IIO_EV_CLASS_<TYPE> etc
The original definitions were duplicated to reduce tree churn during introduction of chan_spec
registration.  Now there is no point in maintaining the two sets of definitions.

6fe8135fcc staging:iio: implement an iio_info structure to take some of the constant elements out of iio_dev.
This was suggested by Arnd Bergmann,  Other elements may well
move in here in future, but it definitely makes sense for these.

6f7c8ee585 staging:iio: Add ability to allocate private data space to iio_allocate_device
Suggested by Arnd Bergmann.  Note this will break ALL drivers that
are out of mainline.  The fix is trivial change of
iio_allocate_device() -> iio_allocate_device(0)
Sorry if this causes issues for any one!
