To provide a new IIO trigger to the IIO core, usually driver executes the following pipeline: allocate()/register()/get(). Before, IIO core assigned trig->owner as a pointer to the module which registered this trigger at the register() stage. But actually the trigger object is owned by the module earlier, on the allocate() stage, when trigger object is successfully allocated for the driver. This patch moves trig->owner initialization from register() stage of trigger initialization pipeline to allocate() stage to eliminate all misunderstandings and time gaps between trigger object creation and owner acquiring.

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.
