[PATCH RFC 0/6] iio: core: Introduce cleanup.h support for mode locks

[Kurt Borja]

Hi,

In a recent driver review discussion [1], Andy Shevchenko suggested we
add cleanup.h support for the lock API:

	iio_device_claim_{direct,buffer_mode}().

Which would allow some nice code simplification* in many places. Some
examples are given as patches, but the last two are the biggest
differences.

Although I was never entirely sure if Andy meant cleanup classes for
locks or for iio_trigger_notify_done(), I still think this is a great
addition to the API :).

Thanks for taking a look!

* It's important to mention that David Lechner expressed some concerns
  about this [2], hence why this is an RFC series.
