So as already mentioned in response to the coverletter of
the first posting of this series.

The drm headers use uint32_t in the prototype definition of the callback
functions we are defining, so the vboxvideo code should use the same even
if the compiler does not warn about the callback implementation having
different parameter types in this case.

To be precise, the page_flip member of struct drm_crtc_funcs is defined as:

        int (*page_flip)(struct drm_crtc *crtc,
                         struct drm_framebuffer *fb,
                         struct drm_pending_vblank_event *event,
                         uint32_t flags,
                         struct drm_modeset_acquire_ctx *ctx);

So our implementation before your patch exactly matches the prototype
which IMHO is the right thing to do.

Regards,

Hans
