[0/9] tty/serial: Termios flag fixes

Message

Here are a few termios flag fixes, mostly CSIZE but a few other flags
as well. The fixed flags returned to userspace should now match to what
the driver is using. Incorrect CSIZE also causes a miscalculation of
timeout in serial core (but it might not be a huge problem being just
a handwavy long timeout).

Ilpo Järvinen (9):
  serial: uartline: Fix BRKINT clearing
  serial: digicolor-usart: Don't allow CS5-6
  serial: rda-uart: Don't allow CS5-6
  serial: txx9: Don't allow CS5-6
  serial: sh-sci: Don't allow CS5-6
  serial: sifive: Sanitize CSIZE and c_iflag
  serial: st-asc: Sanitize CSIZE and correct PARENB for CS7
  serial: stm32-usart: Correct CSIZE, bits, and parity
  pcmcia: synclink_cs: Don't allow CS5-6
