tty: serial: simplify getting .drvdata

2018-04-22T15:29:43Z

We should get drvdata from struct device directly. Going via platform_device is an unneeded step back and forth. Signed-off-by: Wolfram Sang Acked-by: Uwe Kleine-König Acked-by: Michal Simek Acked-by: Patrice Chotard Signed-off-by: Greg Kroah-Hartman

tty: st-asc: Update tty alias

2018-03-14T13:57:04Z

Since dtc v1.4.6-9-gaadd0b65c987, aliases property name must include only lowercase and '-'. After having updated all STi boards serial aliases from "ttyASN" to "serialN", st-asc driver need to be updated accordingly as tty aliases id is retrieved using of_alias_get_id().

tty: serial: Remove redundant license text

2017-11-08T12:08:12Z

Now that the SPDX tag is in all tty files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

tty: add SPDX identifiers to all remaining files in drivers/tty/

2017-11-08T12:08:12Z

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/tty files files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

format-security: move static strings to const

2017-05-09T00:15:14Z

While examining output from trial builds with -Wformat-security enabled, many strings were found that should be defined as "const", or as a char array instead of char pointer. This makes some static analysis easier, by producing fewer false positives. As these are all trivial changes, it seemed best to put them all in a single patch rather than chopping them up per maintainer.
