The return value from the call to sof_ipc4_get_valid_bits() is int. However, the return value is being assigned to an unsigned int variable 'out_ref_valid_bits', so making it an int.
Eliminate the following warning: ./sound/soc/sof/ipc4-topology.c:1537:6-24: WARNING: Unsigned expression compared with zero: out_ref_valid_bits < 0
