The DPC submodule is a part of the atmel-isc pipeline, and stands for Defective Pixel Correction. Its purpose is to detect defective pixels and correct them if possible with the help of adjacent pixels. Create a product specific callback for initializing the DPC submodule of the pipeline. For sama5d2 product, this module does not exist, thus this function is a noop.
