From: Laurent Pinchart Date: Wed, 5 Aug 2015 20:14:41 +0000 (-0300) Subject: [media] v4l: vsp1: Don't validate links when the userspace API is disabled X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=babca007e7c7943215052c95bebfdaac0ca0db7c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [media] v4l: vsp1: Don't validate links when the userspace API is disabled As the pipeline is configured internally by the driver when the userspace API is disabled its configuration can be trusted and link validation isn't needed.
