Subject: [PATCH 0/7] iio: buffer: document calling context when pushing to
 buffers

It came up in a recent discussion [1] that we need to be careful about
the calling context for various iio_push_to_buffer*() functions. Here is
a series that adds some documentation in a number of places to make this
a bit more visible.
