The port count of the PX-257 Rev3 is actually 2, not 4.
Fixes: ef5a03a26c87 ("tty: 8250: Add support for Brainboxes PX cards.") Cc: stable@vger.kernel.org Signed-off-by: Cameron Williams cang1@live.co.uk --- For stable: This patch is only applicable to 5.15 LTS and up, other LTS kernels dont have PX card support.
v3 - v4: Split patch v3 part 5 into multiple Fixes patches and an Additions patch. Add Fixes: and Cc: tag.
v2 - v3: Alter commit message a little to make the additions/fixes cleaner Re-submit patch series using git send-email to make threading work.
v1 - v2: This is a resubmission series for the patch series below. That series was lots of changes sent to lots of maintainers, this series is just for the tty/serial/8250 subsystem.
