From 1e0eded5bb2aa3c2bef95b01a60f2cd4f1d8939f Mon Sep 17 00:00:00 2001
From: Amber Lin <Amber.Lin@amd.com>
Date: Thu, 13 Dec 2018 11:57:35 -0500
Subject: [PATCH 2731/2940] drm/amdgpu: Relocate kgd2kfd function declaration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since amdkfd is merged into amdgpu module and amdgpu can access amdkfd
directly, move declaration of kgd2kfd functions from kfd_priv.h to
amdgpu_amdkfd.h
