Re: [PATCH v3 00/10] media: ov5645: Add support for streams

[Laurent Pinchart <laurent.pinchart@ideasonboard.com>]

Hi Prabhakar,

Thank you for the patches.

I think patch 01/10 should be dropped in favour of
https://lore.kernel.org/r/20241020164354.GG7770@pendragon.ideasonboard.com
("[PATCH v2] media: v4l2-subdev: Refactor events"). Patches 02/10 to
08/10 seem ready, should we merge them without waiting for 09/10 and
10/10 ?
