In order to keep backwards compatibility with the current chardev mechanism, and in order to add support for multiple buffers per IIO device, we need to pass both the IIO device & IIO buffer to the chardev. This is particularly needed for the iio_buffer_read_outer() function, where we need to pass another buffer object than 'indio_dev->buffer'. Since we'll also open some chardevs via anon inodes, we can pass extra buffers in that function by assigning another object to the iio_dev_buffer_pair object.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
