drm/msm/a6xx: Don't enable GPU state code if dependencies are missing
Add CONFIG_DRM_MSM_GPU_STATE to conditionally compile Adreno GPU state code depending on the availability of the dependencies. Reported-by: Hulk Robot <hulkci@huawei.com> Reported-by: YueHaibing <yuehaibing@huawei.com> Fixes: 1707add81551 ("drm/msm/a6xx: Add a6xx gpu state") Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>
