The recent code refactoring made the argument for some helper functions to be the explicit UAC_CS_* and UAC2_CS_* value instead of 0-based offset. However, there was one place left forgotten, and it caused a regression on some devices appearing as the inconsistent mixer setup.
This patch corrects the forgotten conversion.

Thanks for the fix, looks correct to me. UAC2 jack detection still works correctly on my device with this patch.
