[-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?
