pps: generators: pps_gen_parport: Switch to use module_parport_driver()

2022-03-18T13:01:19Z

Switch to use module_parport_driver() to reduce boilerplate code. Note, it doesn't matter when we check the module parameter. If it was writable we even would have more flexibility of changing it at runtime (when built-in the kernel) after this patch.

pps: clients: gpio: Propagate return value from pps_gpio_probe

2022-02-04T14:33:42Z

If the pps-gpio driver was probed prior to the GPIO device it uses, the devm_gpiod_get call returned an -EPROBE_DEFER error, but pps_gpio_probe replaced that error code with -EINVAL, causing the pps-gpio probe to fail and not be retried later. Propagate the error return value so that deferred probe works properly.

tty: no checking of tty_unregister_ldisc

2021-05-13T14:57:17Z

tty_unregister_ldisc now returns 0 = success. No need to check the return value. In fact, the users only warned if an error occured and didn't do anything useful anyway -- the ldisc module was unloaded in any case.

tty: make tty_ldisc_ops a param in tty_unregister_ldisc

2021-05-13T14:57:16Z

Make tty_unregister_ldisc symmetric to tty_register_ldisc by accepting struct tty_ldisc_ops as a parameter instead of ldisc number. This avoids checking of the ldisc number bounds in tty_unregister_ldisc.

tty: set tty_ldisc_ops::num statically

2021-05-13T14:57:16Z

There is no reason to pass the ldisc number to tty_register_ldisc separately. Just set it in the already defined tty_ldisc_ops in all the ldiscs. This simplifies tty_register_ldisc a bit too (no need to set the num member there).

Pull tty and serial driver updates from Greg KH: "Here is the big set of tty and serial driver updates for 5.13-rc1. Actually busy this release, with a number of cleanups happening: - much needed core tty cleanups by Jiri Slaby - removal of unused and orphaned old-style serial drivers. If anyone shows up with this hardware, it is trivial to restore these but we really do not think they are in use anymore. - fixes and cleanups from Johan Hovold on a number of termios setting corner cases that loads of drivers got wrong as well as removing unneeded code due to tty core changes from long ago that were never propagated out to the drivers - loads of platform-specific serial port driver updates and fixes - coding style cleanups and other small fixes and updates all over the tty/serial tree.
