Thank you,

I tried to apply this patch to 6.12.39, the first problematic kernel, as
well as 6.12.41, the first bad I tried, and on both I got an error message:

Applying: HID: quirks: Add device descriptor for 4c4a:4155
error: patch failed: drivers/hid/hid-quirks.c:1068
error: drivers/hid/hid-quirks.c: patch does not apply
Patch failed at 0001 HID: quirks: Add device descriptor for 4c4a:4155

To which kernel version should I apply the patch?

As the deveopment goes from mainline then down to stable series, the
fix needs to be developed first for mainline. So the patch is targeted
there.

But please find attached an updated patch which hopefully should work
which resolved the context changes.

But ideally you can provide a Tested-by on zhangheng's mainline patch
to get things rolling as needed.

Salvatore
