Subject: [PATCH AUTOSEL 6.5 38/52] drm/amdgpu: Unset context priority is now invalid

From: Luben Tuikov <luben.tuikov@....com>

[ Upstream commit eab0261967aeab528db4d0a51806df8209aec179 ]

A context priority value of AMD_CTX_PRIORITY_UNSET is now invalid--instead of
carrying it around and passing it to the Direct Rendering Manager--and it
becomes AMD_CTX_PRIORITY_NORMAL in amdgpu_ctx_ioctl(), the gateway to context
creation.
