Subject: [PATCH 2871/2940] drm/amdgpu: extend AMDGPU_CTX_PRIORITY_NORMAL
 comment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the AMDGPU_CTX_PRIORITY_* defines are used in both
drm_amdgpu_ctx_in::priority and drm_amdgpu_sched_in::priority.

Extend the comment to mention the CAP_SYS_NICE or DRM_MASTER requirement
is only applicable with the former.
