We will send another patch to fix the issue about the "Failed to add route" error.
Tested-by: Stephen Warren swarren@nvidia.com
(On NVIDIA Tegra Beaver/RT5640, Dalmore/RT5640, Jetson TK1/RT5639)
Note that this patch alone (on top of next-20140429) completely eliminates any of the "failed to add route" errors that I mentioned earlier, although perhaps there's still a need to investigate why they happened.
The "failed to add route" errors is coming from we didn't handle a default case when determining which codec is attached. As a result, no _dapm_new_controls is called. That's why once we can determine codecs properly, the errors will be gone. Actually, there are only three possible ID values, and all of them are in the switch cases now. So, I am thinking if we need to add a default case to handle unexpected cases.
