Nathan Chancellor 5ab5e4e60a drm/amd/display: Add a conversion function for transmitter and phy_id enums 
Clang warns:

../drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:2520:42:
error: implicit conversion from enumeration type 'enum transmitter' to
different enumeration type 'enum physical_phy_id'
[-Werror,-Wenum-conversion]
        psr_context->smuPhyId = link->link_enc->transmitter;
                              ~ ~~~~~~~~~~~~~~~~^~~~~~~~~~~
1 error generated.

As the comment above this assignment states, this is intentional. To
match previous warnings of this nature, add a conversion function that
explicitly converts between the enums and warns when there is a
mismatch.

See commit 828cfa2909 ("drm/amdgpu: Fix amdgpu ras to ta enums
conversion") and commit d9ec5cfd5a ("drm/amd/display: Use switch table
for dc_to_smu_clock_type") for previous examples of this.

v2: use PHYLD_UNKNOWN for the default 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.
