[PATCH v2 09/17] rcar-vin: decrease buffers needed to capture

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Niklas Söderlund <niklas.soderlund+renesas@xxxxxxxxxxxx>

It's possible to grab frames using only one buffer, this should never
have been set to anything else then 1.
