Johan writes: USB-serial updates for v4.12-rc1 Here are the USB-serial updates for 4.12, including: - support for devices with up to 16 ports (e.g. some Moxa devices) - support for endpoint sanity checks in core, which allows for code sharing and avoids allocating resources for rejected interfaces - support for endpoint-port remapping, which allows some driver hacks to be removed as well as omninet to use the generic write implementation - removal of an obsolete tty open-race workaround which prevented a port from being opened immediately after having been registered - generic-driver support for interfaces with just a bulk-in endpoint - improved ftdi_sio event-char and latency-timer handling - improved ftdi_sio support for some broken BM chips Included are also various clean ups and a new ftdi_sio device id. All have been in linux-next with no reported issues. Signed-off-by: Johan Hovold <johan@kernel.org>
