The __packed macro isn't available in userspace with the kernel headers. Checkpatch asks to use the macro, which is unwanted in a case of a UAPI header. There is no much benefit in a tight packing of the structures, hence let's pack them manually to cleanup things a tad. Note that there is no old-stable userspace that will suffer from this change, hence it's fine to change the ABI. In a result also more space is reserved for a possible future expansion of the UAPI as it was already shown that more fields will be needed for a later SoC generations.

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.
