LLVM's assembler doesn't accept the short form INL instruction:
inl (%%dx)
but instead insists on the output register to be explicitly specified:
<inline asm>:1:7: error: invalid operand for instruction
inl (%dx)
^
LLVM ERROR: Error parsing inline asm
Use the full form of the instruction to fix the build.

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.
