Hello, This small patch series applies on top of Tomi's multiplexed streams v10 series ("[PATCH v10 00/38] v4l: subdev internal routing and streams", available from [1]). It contains a small fix in 1/2 and a proposed improvement in 2/2. Please see individual patches for details. Jacopo, patch 2/2 may be helpful for your MAX9286 work. If it isn't, I can try to improve it :-) [1] https://lore.kernel.org/all/20211130141536.891878-1-tomi.valkeinen@xxxxxxxxxxxxxxxx/ Laurent Pinchart (2): media: subdev: Rename v4l2_state_get_stream_format() with subdev prefix media: subdev: Extend routing validation helper drivers/media/v4l2-core/v4l2-subdev.c | 111 ++++++++++++++++++++++---- include/media/v4l2-subdev.h | 47 ++++++++--- 2 files changed, 132 insertions(+), 26 deletions(-) -- Regards, Laurent Pinchart
