V4L/DVB (12518): ov772x: S_CROP must return actually configured geometry
V4L2 drivers are allowed to configure a geometry different than what has been requested by the user with S_CROP, but then they have to adjust the input rectangle accordingly. Fix ov772x to comply with this requirement. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
