+Subject: [PATCH 177/247] media: atmel: atmel-isc: create callback for DPC
+ submodule product specific
+
+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.
