Subject: [PATCH v3 01/12] media: sun6i-csi: bridge: Fix return code handling in stream off path

Explicitly set ret to zero on disable path to avoid a related smatch
warning. This makes initialization at declaration useless.

Fixes: 0d2b746b1bef ("media: sun6i-csi: Add bridge v4l2 subdev with port management")
