media: coda: jpeg: start streaming without valid header
Stop bailing out on JPEG header parsing errors during streamon. This allows userspace to provide valid output buffers later and fixes a v4l2-compliance streaming test failure: fail: v4l2-test-buffers.cpp(1429): node->streamon(q.g_type()) test MMAP (no poll): FAIL Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
