tty: Convert ->dtr_rts() to take bool argument

2023-01-19T15:04:35+00:00

Convert the raise/on parameter in ->dtr_rts() to bool through the
callchain. The parameter is used like bool. In USB serial, there
remains a few implicit bool -> larger type conversions because some
devices use u8 in their control messages.

In moxa_tiocmget(), dtr variable was reused for line status which
requires int so use a separate variable for status.

tty: Convert ->carrier_raised() and callchains to bool

2023-01-19T15:04:35+00:00

Return boolean from ->carrier_raised() instead of 0 and 1. Make the
return type change also to tty_port_carrier_raised() that makes the
->carrier_raised() call (+ cd variable in moxa into which its return
value is stored).

Also cleans up a few unnecessary constructs related to this change:

	return xx ? 1 : 0;
	-> return xx;

	if (xx)
		return 1;
	return 0;
	-> return xx;

tty: moxa: Make local var storing tty_port_initialized() bool

2023-01-19T15:04:34+00:00

Return type of tty_port_initialized() is bool, use matching type for
the local variable.

Also reorder the local vars to reverse-xmas-tree while at it.

tty: Make ->set_termios() old ktermios const

2022-08-30T12:22:35+00:00

There should be no reason to adjust old ktermios which is going to get
discarded anyway.

tty: drivers/tty/, stop using tty_schedule_flip()

2021-11-25T17:35:23+00:00

Since commit a9c3f68f3cd8d (tty: Fix low_latency BUG) in 2014,
tty_flip_buffer_push() is only a wrapper to tty_schedule_flip(). We are
going to remove the latter (as it is used less), so call the former in
drivers/tty/.

tty: moxa: merge moxa.h into moxa.c

2021-09-14T09:17:27+00:00

There is no need for existence of a separate header for Moxa's Intellio
cards. Merge it into moxa.c to clean up the tty dir a bit.

tty: moxa: use semi-colons instead of commas

2021-08-26T12:48:07+00:00

This code works but it's cleaner to use a semi-colon to end a statement
instead of a comma.

tty: drop put_tty_driver

2021-07-27T10:17:21+00:00

put_tty_driver() is an alias for tty_driver_kref_put(). There is no need
for two exported identical functions, therefore switch all users of
old put_tty_driver() to new tty_driver_kref_put() and remove the former
for good.
