This is really a simple function, but using it avoids to have
if's inside the drivers.
Also, the kABI becomes a little more clearer.
This shouldn't generate any overhead, and the type check
will happen when compiling with MC DVB enabled.
So, let's do it.

Does "#define dvb_register_media_controller(a, b) {}" restrict the
number of registerd controllers in any way?
I mean, I've got a couple of TBS quad adapters, 4 tuner and 4 demod
chips on each card. Will they still work with this change?

No. What the above define does is to replace the function call by nothing,
if MEDIA_CONTROLLER_DVB is not set.
Neither it or the current patches for the media controller on DVB should
affect the TBS quad adapters. If you're having some regressions with it,
please report.
Regards,
Mauro

Thanks for your reply, I will test this for regression as soon as it
hits the master branch.

Hi Mauro,
I tested this an I've got no issues to report.
If I was in the position to do so, I'd ack these patches.
