journalctl logs of ucsi_acpi errors

So far (kernels 6.11/6.12 up to 6.12.4) I have had an error in the dmesg ("before" section of log.txt)

On the other hand, updating to kernel 6.12.5 (specifically, this commit: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=c0ca6fd5f6ebde8fc0df8bb5c32629d1284f60d0) resulted in a change in the error and the frequency of reporting this to journalctl ("after" section of log.txt)
Comment 1 Piotr Gorski 2024-12-17 16:13:25 UTC 
I checked and the error from the ‘before’ section of the log1.txt file has been around since at least kernel 6.6.
