[PATCH 4.19 082/247] media: vsp1: Fix an error handling path in the probe function

From: Greg Kroah-Hartman
Date: Mon Mar 01 2021 - 15:20:38 EST


From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 7113469dafc2d545fa4fa9bc649c31dc27db492e ]

A previous 'rcar_fcp_get()' call must be undone in the error handling path,
as already done in the remove function.

Fixes: 94fcdf829793 ("[media] v4l: vsp1: Add FCP support")
