tty: serial: fsl_lpuart: Fix unused variable 'sport' build warning (2025-03-24 06:27:10 -0700)
----------------------------------------------------------------
TTY/Serial driver updates for 6.15-rc1
Here is the big set of serial and tty driver updates for 6.15-rc1.
Include in here are the following:
- more great tty layer cleanups from Jiri. Someday this will be done,
but that's not going to be any year soon...
- kdb debug driver reverts to fix a reported issue
- lots of .dts binding updates for different devices with serial
devices
- lots of tiny updates and tweaks and a few bugfixes for different
serial drivers.
All of these have been in linux-next for a while with no reported
issues.
