Get rid of the not needed val local variable and pass the constant value directly as operand value. In addition this turns the val operand into an input operand, since it is not changed within the inline assemblies. This in turn requires also to add the earlyclobber contraint modifier to all output operands, since the (former) val operand is used after all output variants have been modified. The usercopy kunit tests still pass after this change.

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.
