[PATCH v4 00/11] tty: 8250: Brainboxes card additions/fixes

[Cameron Williams]

This patch series fixes up various issues and adds additional support for
cards from the Brainboxes PCI/e serial range.

This series should be suitable for the stable kernels too, though some of
the patches are only applicable for 5.15 LTS and above. The patches where
this is the case have a note explaining why.

Thanks to the reviewers for the feedback thus far.

Change from v3 [1][2][3][4][5][6][7][8]:
- Split up patches to have Fixes and Additions separate
- Add Fixes: tags where neccesary
- Add Cc: for stable

Change from v2 [1][2][3][4][5][6][7]:
- No code changes
- Amend patch 1 and 5 commit comment to better clarify what has been
changed and why
- Send using git send-email instead of Mutt so (hopefully) the
threading works OK

Change from v1 [1][2][3][4]:
- Split the patch into multiple commits for one subsystem/maintainer
rather than a large series for multiple subsystems.
