Re: [PATCH 03/13] drm/amdgpu/mes11: add conversion for priority levels

[Khatri, Sunil]

Do you expect priority level in MES11 12 and probably 13 too ? If they 
are same then we should be using the same conversion function for all 
versions of MES. For now its fine.

Convert driver priority levels to MES11 priority levels.
At the moment they are the same, but they may not always
be.
