Without this, I see a randconfig link failure:
aarch64-linux-ld: drivers/media/platform/rcar_drif.o: in function `rcar_drif_remove': rcar_drif.c:(.text+0x2a8): undefined reference to `v4l2_async_notifier_unregister' aarch64-linux-ld: rcar_drif.c:(.text+0x2b0): undefined reference to `v4l2_async_notifier_cleanup' aarch64-linux-ld: drivers/media/platform/rcar_drif.o: in function `rcar_drif_sdr_probe': rcar_drif.c:(.text+0x1444): undefined reference to `v4l2_async_notifier_init' aarch64-linux-ld: rcar_drif.c:(.text+0x14a0): undefined reference to `v4l2_async_notifier_register' aarch64-linux-ld: rcar_drif.c:(.text+0x14d8): undefined reference to `v4l2_async_notifier_cleanup' aarch64-linux-ld: rcar_drif.c:(.text+0x15a8): undefined reference to `__v4l2_async_notifier_add_fwnode_subdev'
I could not easily figure out when this was introduced, as this code has not changed in a while but I only saw the problem recently.
