the patch i used to patch the manjaro kernel

First time reporting a bug on Bugzilla. I have looked at the most recent version of the source on GitHub and it does not include the fix i need (https://github.com/torvalds/linux/blob/master/sound/soc/amd/yc/acp6x-mach.c)

i am running kernel version 6.6.12-1-MANJARO

there are no steps to reproduce. the mic just does not show up even though there is a module loaded for the ACP6X device. 

I have patched the kernel and it does work. 

expected result of `arecord -l`

Can you submit the patch to LKML (see Documentation/process/submitting-patches.rst for instructions)?

I dont think gmail works with the mailing list, hence why i made a bugzilla report. I'm not really a kernel developer so I am hesitent to go through all the hubub to get something setup just for this patch.
