[PATCH 0/2] docs: iio: update dated triggered buffer example

[David Lechner]

Noticed this example was out of date while grepping for something else.
And when I did get_maintainer.pl on it, it didn't match the IIO
subsystem, so we get a bonus patch to fix that too.

[PATCH 2/2] docs: iio: triggered-buffers: use new helpers in example

[David Lechner]

Update the "typical" triggered buffer example to use various new helpers
that have been added in the last year or so. This reflects current
expectations of how similar code should be written.

Also zero-initialize the buffer so we don't leak stack data. And fix a
missing semicolon while we're at it.

Well I suppose we 'should' maintain those :)

Series applied.
