Hi,

this is another series of various cleanup in tty of issues which popped
up at me during a larger rework.

Jiri Slaby (SUSE) (6):
  tty: simplify throttling using guard()s
  tty: use lock guard()s in tty_io
  serial: switch uart_port::iotype to enum uart_iotype
  serial: rename local uart_port_lock() -> uart_port_ref_lock()
  serial: use uart_port_ref_lock() helper
  serial: 8250: unexport serial8250_rpm_*() functions
