Is it safe to change that ? Not sure. Might as well leave it at -1, we define the default in the DT anyway. CU Uli

[PATCH 2/2] media: adv7604: automatic "default-input" selection
Fall back to input 0 if "default-input" property is not present. Documentation states that the "default-input" property should reside directly in the node for adv7612. Hence, also adjust the parsing to make the implementation consistent with this. Based on patch by William Towle .
