Subject: [PATCH v2 01/27] media: ca.h: split typedefs from structs
Using typedefs inside the Kernel is against CodingStyle, and
there's no good usage here.
Just like we did at frontend.h, at changeset 0df289a209e0
("[media] dvb: Get rid of typedev usage for enums"), let's keep
those typedefs only to provide userspace backward compatibility.
No functional changes.
