The pattern used in this device does not quite fit in the iio_device_claim_direct_mode() typical usage. In this case, iio_buffer_enabled() was being used not to prevent the raw access but to allow it. Hence, let's make use of the new iio_device_claim_buffer_mode() API to make sure we stay in buffered mode during the complete read. Note that we are shadowing the error code returned by iio_device_claim_buffer_mode() so that we keep the original one (-EAGAIN). The reason is that some userspace stack might already be relying on this particular code so that we are not taking chances and leave it alone.

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.
