This switch statement, and all the similar code below, is another instance of the internal-API problem.

You have one multiplexer function that switches among primary, overlay and cursor planes. You've replicated the functionality of the DRM core and helpers in your driver.

It is much better to implement a function for each type of plane: vs_dc_update_primary_plane(), vs_dc_update_overlay_plane(), vs_dc_update_cursor_plane(). Then make an instance of drm_plane_helper_func for each type of plane:

struct drm_plane_helper_funcs primary_plane_helpers = {
vs_dc_update_primary_plane
};

struct drm_plane_helper_funcs overlay_plane_helpers = {
vs_dc_update_overlay_plane
};

struct drm_plane_helper_funcs cursor_plane_helpers = {
vs_dc_update_cursor_plane
};

Each of these helper_funcs instances handle exactly their own type of plane. When you create your modesetting pipeline, just use the correct helpers for each instanciated plane. You'll have less boiler plate code, less indirection, and adding new and different planes is really easy.
