OpenWFD Initialization fails

Wfd initialization code calls multiple of enumerate functions such as WfdEnumerateDevices.
According to Wfd -API, the enumerate functions return zero whenever there is an error. Currently the functions are checking that the return value is != WFD_ERROR_NONE, which effectively means that enumerate call will result in a exception every time the function actually was executed successfully.

Following function call return values are currently erroneous in the OpenWFD-adaptation:
wfdEnumerateDevices

wfdEnumeratePorts

wfdGetPortModes

wfdEnumeratePipelines
