From: Laurent Pinchart <laurent.pinchart@ideasonboard.com> [ Upstream commit cc271b6754691af74d710b761eaf027e3743e243 ] The correct return code to report an invalid pipeline configuration is -EPIPE. Return it instead of -EINVAL from __capture_legacy_try_fmt() when the capture format doesn't match the media bus format of the connected subdev.
