Subject: [PATCH] media: imx7-mipi-csis: remove subdev_notifier
Git-commit: 06b5cf51607da6bec60815954487e96012d5f8ee
Patch-mainline: v5.6-rc1
References: git-fixes

It was defined a notifier in the csi_state structure that is never
allocated. And besides that it's unregister in the remove, even though
it is a no-op, just remove both.
