Merge branch 'drm-fixes-4.14' of git://people.freedesktop.org/~agd5f/linux into drm-fixes
Just two small patches for stable to fix the driver failing to load on polaris cards with harvested VCE or UVD blocks. * 'drm-fixes-4.14' of git://people.freedesktop.org/~agd5f/linux: drm/amdgpu: allow harvesting check for Polaris VCE drm/amdgpu: return -ENOENT from uvd 6.0 early init for harvesting
