From: Niklas Söderlund <niklas.soderlund+renesas@xxxxxxxxxxxx> Hi, This series enables incremental async find and bind of subdevices, please se patch 2/2 for a more detailed description. This is tested on Renesas H3 and M3-W together with the Renesas CSI-2 and VIN Gen3 driver (posted separately). It is based on top of Sakaris pull request '[GIT PULL FOR v4.13] V4L2 fwnode support'. While this series do not require the fwnode support the code that makes us of this feature do. Changes since v1: - Added a pre-patch which adds an error check which was previously in the new incremental async code but is more useful on its own. - Added documentation to Documentation/media/kapi/v4l2-subdev.rst. - Fixed data type of bool variable. - Added call to lockdep_assert_held(), thanks Sakari. - Fixed commit messages typo, thanks Sakari.
