Lan7431 - vanilla driver of Lan7431 from upstream
Adding unmodified Lan7431 driver to nvidia-oot This is the unmodified driver from K5.15.110 from commit cd612ec8f71740b0fc9f47d3356b23561b5761dc For future kernels we'll need to add the driver sources from the respective kernel Bug 3956901 Change-Id: I376c63ceeb6aeab9ce5d17dcd3c09401217c576a Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/2920947 GVS: Gerrit_Virtual_Submit <buildbot_gerritrpt@nvidia.com> Tested-by: Jeremy Alves <jalves@nvidia.com> Reviewed-by: Jeremy Alves <jalves@nvidia.com> Reviewed-by: Sumeet Gupta <sumeetg@nvidia.com>
