From: Varad Gautam <varad.gau...@collabora.com>
return the modifier selected by the driver when creating this image.
v2: since we can use winsys_handle->modifier to serve these, remove
DRIimage->modifier from v1.
use DRM_API_HANDLE_TYPE_KMS instead of DRM_API_HANDLE_TYPE_FD to avoid
ownership transfer. (Lucas)
