Hi Steve,
Just to let you know that this series no longer apply clean after
your other series:
media: imx: Fix subdev unregister/register issues
And since you will need to send a new one, some notes...

instead of adding this between structs declaration can you move it
down near the similar converter:
static struct csi_state *mipi_sd_to_csis_state(struct v4l2_subdev *sdev)
and remove the inline since the compiler should do this and add
namespacing function name like the other functions, something like:
static struct csi_state * mipi_notifier_to_csis_state(struct
v4l2_async_notifier *n)
Just to coherency.
Other than this, looks good to me.
Cheers,
Rui
