Another possible solution... This is my last one, I promise :-)
I looked at dvb_attach() and realized that you can ab^H^Hreuse it. This
makes the patch tiny, and allow you to continue hiding
struct cxd2820r_priv.

Subject: [PATCH] em28xx-dvb: Use dvb_attach to call cxd2820r_get_tuner_i2c_adapter()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This avoids a hard module dependency on cxd2820r. Even though we
don't really attach anything in this call, we can stil reuse
dvb_attach since the called function is expected to return a
pointer.
