ITE-CIR Overflow - how do these patches make it into Arch?

Hello-
One of my systems has been having problems with the infrared receiver;
ir-keytable stops displaying output in test mode, particularly after 'overflow' messages are logged by the kernel in syslog.  This happens for me after only seconds to minutes of the unit being powered on.

Research on the internet when it first started happening, I found these postings that align with the symptoms:
https://bugs.debian.org/cgi-bin/bugrepo … =996672#27
https://lore.kernel.org/linux-media/202 … @mess.org/

I generally keep the system up to date, so believe it is running kernel 5.16.13, or one version previous. I can grab that information and provide it tomorrow.

How do patches end up folded into Arch?  IIRC Arch uses primarily upstream with minimal patching.

I've continued to have this problem through all updates;  Can anyone tell me how to find out when this  patch has been applied to arch or upstream? 

many thanks

Re: ITE-CIR Overflow - how do these patches make it into Arch?

Searching for the commit message I found https://github.com/torvalds/linux/commi … 1c8766d12a shows it was merged into 5.16 so will be present in all 5.16.Y releases.
For linux-lts:

$ git log --oneline --grep=fdc881783099c6343921ff017450831c8766d12a v5.15.27
2837d7277ea1 media: ite-cir: IR receiver stop working after receive overflow
$ git tag --contains 2837d7277ea1
...
v5.15.3

Thank you for the information-
Unfortunately i've managed to break my vmlinuz installation somehow and can't verify..

Will come back once i get my system operational again.

Finally got it working again (had some issues with corrupt vmlinuz-linux for some reason)

I'm running:
Linux kodiarch 5.16.14-arch1-1 #1 SMP PREEMPT Fri, 11 Mar 2022 17:40:36 +0000 x86_64 GNU/Linux

Well, heck. i'm still having a similar if not the same problem.
On reboot, the remote works for a little while-
but then stops working, and in that time dmesg just starts dumping

Hmm i'll have to chase more upstream or something i guess.
Thank you.
