The file is specific to each hardware design. Normally, the board designer should add a line in the of_device_id table with his own antenna parameters. Until, now the absence of PDS file is a hard fatal error. However, during the development, in most of the cases, an empty PDS file is sufficient to start WiFi communication. This patch keep an error, but allow the user to play with the device.
