Linux kernel source tree

The reg >= 0 check in reg_is_mmio is unnecessary because reg is always greater than zero in all current use cases. This is obvious when checking 'offset' by itself (as offset is defined as an unsigned integer), but it's also true for the offset + bytes - 1 use case in intel_vgpu_emulate_mmio_read because bytes > 0.

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 reStructuredText 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.
