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