Matt Coffin eb696d041f drm/amdgpu/smu: Add message sending lock
This adds a message lock to the smu_send_smc_msg* implementations to
protect against concurrent access to the mmu registers used to
communicate with the SMU

v2: Implement for smu_v12_0 as well

v3: Add mutex_init for message_lock

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.
