[PATCH v2] ASoC: hdac_hdmi: convert num_nodes to int

[Sudip Mukherjee]

All uses of num_nodes are considering it as a signed integer and that is
very much clear when we try to save the error value in it and later try
to compare it with less than 0.

No.  The point is that the value checked *there* has to be int, not
the value used for the success case.  Just have a temporary value,
e.g. int num_nodes, assign there, check it, then assign the value to
codec->num_nodes field.  The num_nodes field itself is obviously an
unsigned.
