   4 Subject: [PATCH 181/247] media: atmel: atmel-isc: create an adapt pipeline
   5  callback for product specific
   6
   7 Once the pipeline is set in the base code, create a callback that will adapt
   8 the ISC pipeline to each product.
   9 Create the adapt_pipeline callback that will be used in this fashion.
