Subject: [PATCH] drm/amdgpu: Fix code with incorrect enum type

Instead of the 'amdgpu_ring_priority_level' type,
the 'amdgpu_gfx_pipe_priority' type was used,
which is an error when setting ring priority.
This is a minor error, but may cause problems in the future.

Instead of AMDGPU_RING_PRIO_2 = 2, we can use AMDGPU_RING_PRIO_MAX = 3,
but AMDGPU_RING_PRIO_2 = 2 is used for compatibility with
AMDGPU_GFX_PIPE_PRIO_HIGH = 2, and not change the behavior of the
code.

gfx_v8_0.c, gfx_v9_0.c, gfx_v10_0.c all do this. Care to fix them all up?

Alex Deucher I will do it. Initially, I came across an error that
different enum types are used.
Now I looked at the files, and indeed AMDGPU_GFX_PIPE_PRIO_* is used
instead of AMDGPU_RING_PRIO_*.
The question remains whether it is worth increasing the priority to
AMDGPU_RING_PRIO_MAX=3 ?

Regards, Grigory.
