With this series I try to finish the task, started with the series [1],
of completely removing the dependency of the slcan driver from the
userspace slcand/slcan_attach applications.

The series also contains patches that remove the legacy stuff (slcan_devs,
SLCAN_MAGIC, ...) and do some module cleanup.

The series has been created on top of the patches:

can: slcan: convert comments to network style comments
can: slcan: slcan_init() convert printk(LEVEL ...) to pr_level()
can: slcan: fix whitespace issues
can: slcan: convert comparison to NULL into !val
can: slcan: clean up if/else
can: slcan: use scnprintf() as a hardening measure
can: slcan: do not report txerr and rxerr during bus-off
can: slcan: do not sleep with a spin lock held

applied to linux-next.

[1] https://lore.kernel.org/all/20220628163137.413025-1-dario.binacchi@amarulasolutions.com/

Changes in v3:
- Update the commit message.
- Use 1 space in front of the =.
- Put the series as RFC again.
- Pick up the patch "can: slcan: use KBUILD_MODNAME and define pr_fmt to replace hardcoded names".
- Add the patch "ethtool: add support to get/set CAN bit time register"
  to the series.
- Add the patch "can: slcan: add support to set bit time register (btr)"
  to the series.
- Replace the link https://marc.info/?l=linux-can&m=165806705927851&w=2 with
  https://lore.kernel.org/all/507b5973-d673-4755-3b64-b41cb9a13b6f@hartkopp.net.
- Add the `Suggested-by' tag.

Changes in v2:
- Re-add headers that export at least one symbol used by the module.
- Update the commit description.
- Drop the old "slcan" name to use the standard canX interface naming.
- Remove comment on listen-only command.
- Update the commit subject and description.
- Add the patch "MAINTAINERS: Add myself as maintainer of the SLCAN driver"
  to the series.

Dario Binacchi (8):
  can: slcan: remove useless header inclusions
  can: slcan: remove legacy infrastructure
  can: slcan: change every `slc' occurrence in `slcan'
  can: slcan: use the generic can_change_mtu()
  can: slcan: add support for listen-only mode
  ethtool: add support to get/set CAN bit time register
  can: slcan: add support to set bit time register (btr)
  MAINTAINERS: Add maintainer for the slcan driver

Vincent Mailhol (1):
  can: slcan: use KBUILD_MODNAME and define pr_fmt to replace hardcoded
    names

No need to change the series to RFC again :)

Please post a v4 with both BTR patches dropped and add Max Staudt's
Reviewed-by to patch 3.
