mxser: Documentation, make the docs up-to-date

2021-06-18T11:10:03Z

Remove all the obsolete information from the documentation of mxser driver. Either it was about the out-of-tree driver, or it was superseded by udev et al. Signed-off-by: Jiri Slaby Link: https://lore.kernel.org/r/20210618061516.662-69-jslaby@suse.cz Signed-off-by: Greg Kroah-Hartman

mxser: Documentation, remove traces of callout device

2021-06-18T11:10:03Z

Callout devices are ancient history, so remove its traces from mxser's documentation. Signed-off-by: Jiri Slaby Link: https://lore.kernel.org/r/20210618061516.662-68-jslaby@suse.cz Signed-off-by: Greg Kroah-Hartman

mxser: drop ISA support

2021-06-18T11:09:58Z

While mxser PCI cards are still around and produced (Moxa provided me with two recently), ISA cards are obsolete for a long time. I haven't seen anyone using the cards and the ISA code paths are barely tested. Hence, remove ISA support from mxser driver so that we can clean the driver up.

Remove link to nonexistent rocket driver docs

2021-05-11T17:02:39Z

The rocket driver and documentation were removed in this commit, but the corresponding entry in index.rst was not removed.

tty: rocket, remove the driver

2021-03-10T08:34:06Z

While the driver is still marked as maintained in MAINTAINERS, Comtrol does not really care about this ancient driver. They are still manufacturing serial devices, but those are controlled only by out-of-tree drivers. Comtrol didn't answer my pings, so this driver is apparently unmaintained. Aside from that, the driver was untouched for years, only whole-tree changes happened during the past years. The driver needs much more care, so drop it for now. If someone steps up to reintroduce it, they need to clean it up first.

tty: cyclades, remove this orphan

2021-03-10T08:34:06Z

The Cyclades driver was orphaned by commit d459883e6c54 (MAINTAINERS: remove two dead e-mail) 13 years ago. Noone stepped up to take care of them and to fix all the issues the driver has. On the top of that, there is no way to obtain the firmware for Z cards from the vendor as cyclades.com ceased to exist. So it's time to drop the driver with all its traces.

tty: vt: Replace HTTP links with HTTPS ones

2020-07-21T18:04:54Z

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

tty: n_gsm: add ioctl to map serial device to mux'ed tty

2019-09-04T10:43:54Z

Guessing the first tty for a gsm0710 multiplexed serial device is not currently possible, which makes it racy to use with multiple modems. Add a way to map the physical serial tty to its related mux devices using an ioctl.
