The "struct i915_syncmap" uses a dynamically sized set of trailing elements. It can use an "u32" array or a "struct i915_syncmap *" array. So, use the preferred way in the kernel declaring flexible arrays [1]. Because there are two possibilities for the trailing arrays, it is necessary to declare a union and use the DECLARE_FLEX_ARRAY macro. The comment can be removed as the union is now clear enough. Also, avoid the open-coded arithmetic in the memory allocator functions [2] using the "struct_size" macro. Moreover, refactor the "__sync_seqno" and "__sync_child" functions due to now it is possible to use the union members added to the structure. This way, it is also possible to avoid the open-coded arithmetic in pointers.

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.
