From e18976eecabd252ca406ae2325e983f8eaa348cd Mon Sep 17 00:00:00 2001 From: =?utf8?q?Niklas=20S=C3=B6derlund?= Date: Fri, 6 Dec 2019 17:39:32 +0100 Subject: [PATCH] media: rcar-vin: Limit NV12 availability to supported VIN channels only MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When adding support for NV12 it was overlooked that the pixel format is only supported on some VIN channels. Fix this by adding a check to only accept NV12 on the supported channels 0, 1, 4, 5, 8, 9, 12 and 13.
