For the record: I have no reason to object a patch that does that. (I'm
not aware anyone complained when gigaset switched its default from i4l
to capi. By now all relevant distributions should use our capi driver.)

> * move i4l core to staging

On a local tree I have two (draft) patches that do some related
preliminary work:
- isdnhdlc: move into separate directory
- mISDN: NETJet: stop selecting ISDN_I4L

These trivial patches untangle mISDN and i4l. Perhaps you did something
similar in your "move i4l core to staging".

See also commit 3460baa62068 ("PCI: Fix minimum allocation address
overwrite").

For my part I'm surprised that anyone is still using it. But apparently
the hardware that required commit 19cebbcb04c8 and 3460baa62068  (which
I'm unfamiliar with) is still operational. And since there never has
been, as far as I know, a global i4l to capi migration nor a global i4l
(and capi) to mISDN migration it might be that some people are stuck on
i4l drivers for their hardware. Perhaps that explains Cristoph's
commits.
