doc: Leftovers from CAPI remove?

[Alexander Dahl]

Hei hei,

when accidentally building an old Fritz PCI driver against v5.6.1 we
hit this build error (which this mail is not about):

/home/florian/.fbr/fbr-4.0-trunk-x86_64/buildroot/output/build/fcpci-2.6-43.x86_64-5.6.1/fritz/src/main.c:371:3:
Fehler: Implizite Deklaration der Funktion Âregister_capi_driverÂ; meinten Sie Âregister_chrdevÂ?  [-Werror=implicit-function-declaration]

A quick grep in master revealed there are still hints to the function
'register_capi_driver()' in file Documentation/isdn/interface_capi.rst

I suppose after removing capi parts with f59aba2f7579 ("isdn: capi:
dead code removal") and merging with 7ba31c3f2f1e ("Merge tag
'staging-5.6-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging") these
are leftovers in the documentation, which should be removed, right?
