The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >>From 714569064adee3c114a2a6490735b94abe269068 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Sat, 3 Feb 2018 12:27:23 +0100 Subject: serial: core: mark port as initialized in autoconfig This is a followup on 44117a1d1732 ("serial: core: mark port as initialized after successful IRQ change"). Nikola has been using autoconfig via setserial and reported a crash similar to what I fixed in the earlier mentioned commit. Here I do the same fixup for the autoconfig. I wasn't sure that this is the right approach. Nikola confirmed that it fixes his crash.
