Subject: [PATCH 159/247] media: atmel: atmel-isc: add checks for limiting
|
|
frame sizes
|
|
|
|
When calling the subdev, certain subdev drivers will overwrite the
|
|
frame size and adding sizes which are beyond the ISC's capabilities.
|
|
Thus we need to ensure the frame size is cropped to the maximum caps.
