Joshua Aberback 254eb07cb0 drm/amd/display: Optimize bandwidth validation by adding early return
We can split validation into three parts: getting voltage level, getting
watermarks, and rq/dlg calculations. The voltage level is enough to answer
the question "do we support this state", and the rest of it is to determine
what hardware programming is needed to support the state. Most of the calls
to validate_bandwidth only care about the first part, so we added an early
return in that case

README

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.
