[PATCH v2 00/41] CAPI: Major rework, tons of bug fixes

[Jan Kiszka <jan.kiszka@web.de>]

Here is the second take of my CAPI rework. I tried to address all
feedback on v1, so this one comes with the following changes:

 o rebased over net-next
 o reworked locking of the NCCI TTY using latest and greatest tty_port
   features and kref, hopefully in the right way
 o more fine-grained patch steps for the tricky TTY rework
 o dynamic major for NCCI TTYs, ie. CAPI no longer claims 191
 o dynamic TTY minor registrations, completely obsoleting capifs
 o schedule capifs for removal
 o some small additional cleanups

I kept my capifs fixes though this thing should die in the future. The
work is done, and people may still use it due to their distro
configuration (and the hard-wired loading by capiinit - needs fixing).
