Subject: [PATCH] media: rcar_drif: select CONFIG_V4L2_ASYNC

From: Arnd Bergmann <[email protected]>

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':

aarch64-linux-ld: rcar_drif.c:(.text+0x14a0): undefined reference to `v4l2_async_notifier_register'

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.
