Hi Alexander, Thanks for the patch. Alexander Stein <alexander.stein@ew.tq-group.com> writes: > Default to non-interleaving. Why? > > Fixes: bc0d3df31ffe ("media: imx: imx7-media-csi: Simplify imx7_csi_video_init_format()") It was never init to FIELD_NONE even before this patch, do you think it is really a fix?

Otherwise it is implicitly set to V4L2_FIELD_ANY as the structure is zero-initialized, and that's not a valid value for drivers to return to userspace. This should be explained in the commit message. > > Fixes: bc0d3df31ffe ("media: imx: imx7-media-csi: Simplify imx7_csi_video_init_format()") > > It was never init to FIELD_NONE even before this patch, do you think it > is really a fix? Commit bc0d3df31ffe does indeed not seem relevant. The problem predates the destaging of the driver, it's a bit difficult to trace.

This should be explained in the commit message. Yes, that was my intention, to have the why in the commit message.
