Subject: [PATCH 0/4] serial: 8250_dw: Rework ->serial_out() & LCR retry logic

This series reworks DW UART's write logic such that the write in
->serial_out() is reused for LCR retries which allows removing those
ugly duplicated writes in dw8250_check_lcr() (renamed to
dw8250_verify_write() by this series).

I've used label+goto since the retry is really an exceptional thing. If
somebody insists, I can convert those to do {} while (); but I feel it
will give wrong impression that there's a "loop" there.

Ilpo Järvinen (4):
  serial: 8250_dw: Use dw8250_serial_out() in dw8250_serial_out38x()
  serial: 8250_dw: Rename offset to reg_offset
  serial: 8250_dw: Move 16550 compatible & LCR checks to
    dw8250_verify_write()
  serial: 8250_dw: Rework ->serial_out() LCR write retry logic
