Subject: [PATCH 5.19 0380/1157] media: rcar-vin: Fix channel routing for Ebisu

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

[ Upstream commit 5b9b598453d3ae5fa66d7ab591008373a89b91a0 ]

When converting to full Virtual Channel routing an error crept into the
routing table for Ebisu (r8a77990). The routing information is used at
probe time preventing rcar-vin from probing correctly on this SoC, solve
by correcting the routing table.

Fixes: 3e52419ec04f9769 ("media: rcar-{csi2,vin}: Move to full Virtual Channel routing per CSI-2 IP")
