In order to drop the internal lock usage we needed two different things: 1) The first place where 'mlock' was being used was a typical case where iio_device_claim_direct_mode() fits perfectly. 2) In the second case, it was being used to prevent concurrent accesses to the device and shared data but nothing was being enforced with regards to buffering (i.e, there was nothing preventing from changing the conversion mode while buffering). Hence, in this case, a new lock was introduced in the state structure. Note that the goal is not to introduce any functional change and that is the reason why a new lock was introduced to guarantee 2). While at it, properly include "mutex.h" for mutex related APIs.

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.
