The B-channels are only accessed via the PCM backplane.
Add infrastruckture for this special mode.

Signed-off-by: Karsten Keil <redacted>

I dread reviewing these ISDN patch sets because they are so
full of problems, and it's so damn obvious how little care is
put into preparing them.

What I see is that you put the minimum amount of work necessary
into splitting up your huge ISDN patch set submission into more
managable pieces, and as a result you are introducing problems.

I did put the additional PCM infrastructure in this series, because
the approval test was done with it in place.
I did plan the update of the low level drivers in a separate patchset
from the beginning.

What do you prefer, adding the driver part now, as additional patch, or
removing this additional infrastruckture part and submit it in a later
series ?

Ok, that's fine.

But what the hell is this?  These structure members are unused by
this patch, and in fact no patch in your entire series uses them.

Another completely unrelated change, nothing in this patch uses

And again, same problem.

You really need to get your act in gear and prepare your patches
properly, so that they don't have unrelated changes in them.

This is not amateur hour.
