Agreed, but it's not the "invalid CONNECT_LIST verb" message you're changing, it's the "invalid dep_range_val" message?
Doh, you're right, just patched a wrong place. The correct one is below.

The zero-length connection list happens so often on Haswell HDMI, and it results in warning messages like ALSA: hda_codec: invalid CONNECT_LIST verb 5[1]:0 at each time the codec resumes from the power-save, which is fairly annoying.
Since this is no real error, make it shown only in the verbose debug mode.
