Subject: [PATCH v2 0/4] ledtrig-tty: add new state evaluation

Changes in v2:
- rename new function from tty_get_mget() to tty_get_tiocm() as
  requested by 'Jiri Slaby'.
- As suggested by 'Jiri Slaby', fixed tabs in function documentation
  throughout the file '/drivers/tty/tty_io.c' in a separate commit.
- Move the variable definition to the top in function 'ledtrig_tty_work()'.
  This was reported by the 'kernel test robot' after my change in v1.
- Also set the 'max_brightness' to 'blink_brightness' if no
  'blink_brightness' was set. This fixes a problem at startup when the
  brightness is still set to 0 and only 'line_*' is evaluated. I looked in
  the netdev trigger and that's exactly how it's done there.

v1:
This is a follow-up patchset, based on the mailing list discussion from
March 2023 based on the old patchset v7 [1]. I have changed, the LED trigger
handling via the sysfs interfaces as suggested by Uwe Kleine-König.
