Merge tag 'usb-serial-4.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into usb-linus
Johan writes: USB-serial fixes for v4.12-rc2 Here's a fix for a long-standing issue in the ftdi_sio driver that prevented unprivileged users from updating the low-latency flag, something which became apparent after a recent change that restored the older setting of not using low-latency mode by default. A run of sparse revealed a couple of endianness issues that are now fixed, and addressed is also a user-triggerable division-by-zero in io_ti when debugging is enabled. Finally there are some new device ids, including a simplification of how we deal with a couple of older Olimex JTAG adapters. All have been in linux-next with no reported issues.
