Subject: [PATCH AUTOSEL 4.19 612/671] media: rcar-vin: Fix incorrect return statement in rvin_try_format()

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

[ Upstream commit a0862a40364e2f87109317e31c51c9d7bc89e33f ]

While refactoring code the return statement became corrupted, fix it by
returning the correct return code.
