Merge tag 'usb-serial-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into usb-next
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.
