2020-07-09USB: serial: ftdi_sio: fix break and sysrq handlingJohan Hovold
Only the last NUL in a packet should be flagged as a break character, for example, to avoid dropping unrelated characters when IGNBRK is set. Also make sysrq work by consuming the break character instead of having it immediately cancel the sysrq request, and by not processing it prematurely to avoid triggering a sysrq based on an unrelated character received in the same packet (which was received *before* the break). Note that the break flag can be left set also for a packet received immediately following a break and that and an ending NUL in such a packet will continue to be reported as a break as there's no good way to tell it apart from an actual break. Tested on FT232R and FT232H.

2020-07-06USB: serial: ch341: simulate break condition if not supportedMichael Hanselmann
A subset of all CH341 devices don't support a real break condition. This fact is already used in the "ch341_detect_quirks" function. With this change a quirk is implemented to simulate a break condition by temporarily lowering the baud rate and sending a NUL byte. The primary drawbacks of this approach are that the duration of the break can't be controlled by userland and that data incoming during a simulated break is corrupted. The "TTY_DRIVER_HARDWARE_BREAK" serial driver flag was investigated as an alternative. It's a driver-wide flag and would've required significant changes to the serial and USB-serial driver frameworks to expose it for individual USB-serial adapters. Tested by sending a break condition and watching the TX pin using an oscilloscope.
