[Adding Tony Prisk and linux-serial]
Hi Roel,
While this looks like a good fix, the commit message is a bit confusing.
How about something like the message between the scissor lines below:
---->8----
[PATCH] serial: vt8500: add missing braces
Due to missing braces on an if statement, port will always be assigned
-1 regardless of any alias entries in the dt, which was clearly not the
intended behaviour.
This patch adds the missing braces, fixing the issue.
---->8----
Also, while this is device tree related, you should Cc the driver
maintainer when submitting driver changes.
Cheers,
Mark.
