Subject: [PATCH 4.19 486/639] media: rcar-vin: Clean up correct notifier in error path

From: Niklas Söderlund <niklas.soderlund+renesas@...natech.se>

[ Upstream commit 0bd465765f8d1300040de627f0a0971a8849d654 ]

The parallel input initialization error path cleans up the wrong
async notifier, fix this by cleaning up the correct notifier.
