Jonathan Cameron 5aa9618896 staging:iio: remove broken support for multiple event interfaces.
We don't have a use case for these.  Two drivers appeared to use them
but both report all events on the first.

V2: Remove now irrelevant comment.
V3: Include fixup for adc/ad7280a.c

Jonathan Cameron 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.

Paul Gortmaker 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.

Jonathan Cameron 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.
