Hi,
This short patchset adds support for the new 16550-compatible
serial port subtype in the spcr.c driver, using the definition from
updated ACPICA header.
I'm looking forward to the comments or remarks.
Best regards,
Marcin

I'm not sure to be aware of the process. Reported where?
Are you planning to import the upstream patch on your own and I should
rebase the SPCR driver change on top once it lands?

The patch was posted as a pull request on our github site.
The merged patch will be released as part of the normal ACPICA release process, which will then make it into Linux. You should then rebase.
