However, the plane size and\nstride values were not updated. So there is a possibility that the buffer might\nbe over-sized for the requested resolution.\n\nFix this by only copying the relevent fields from the ISP Output 0\nV4L2DeviceFormat structure, and let the device driver size the planes as needed.\n\nSigned-off-by: Naushir Patuck <naush@raspberrypi.com>\n---\n src/libcamera/pipeline/raspberrypi/raspberrypi.cpp | 4 +++-\n 1 file changed, 3 insertions(+), 1 deletion(-)",
