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. Reviewed-by: Andy Shevchenko Signed-off-by: Ilpo Järvinen Link: https://lore.kernel.org/r/20220816115739.10928-9-ilpo.jarvinen@linux.intel.com Signed-off-by: Greg Kroah-Hartman

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.

tty: stop using alloc_tty_driver

2021-07-27T10:17:20+00:00

alloc_tty_driver was deprecated by tty_alloc_driver in commit 7f0bc6a68ed9 (TTY: pass flags to alloc_tty_driver) in 2012. I never got into eliminating alloc_tty_driver until now. So we still have two functions for allocating drivers which might be confusing. So get rid of alloc_tty_driver uses to eliminate it for good in the next patch. Note we need to switch return value checking as tty_alloc_driver uses ERR_PTR. And flags are now a parameter of tty_alloc_driver.

tty: don't store semi-state into tty drivers

2021-07-27T10:17:20+00:00

When a tty driver pointer is used as a return value of struct console's device() hook, don't store a semi-state into global variable which holds the tty driver. It could mean console::device() would return a bogus value. This is important esp. after the next patch where we switch from alloc_tty_driver to tty_alloc_driver. tty_alloc_driver returns ERR_PTR in case of error and that might have unexpected results as the code doesn't expect this.
