[PATCH 5.0 180/238] media: cx25840: mark pad sig_types to fix cx231xx init

[Greg Kroah-Hartman]

5.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Cody P Schafer <dev@xxxxxxxxxx>

commit 46c039d06b6ecabb94bd16c3a999b28dc83b79ce upstream.

Without this, we get failures like this when the kernel attempts to
initialize a cx231xx device:

	[16046.153653] cx231xx 3-1.2:1.1: New device Hauppauge Hauppauge Device @ 480 Mbps (2040:c200) with 6 interfaces

	[16048.568579] cx231xx 3-1.2:1.1: V4L2 device video2 deregistered
	[16048.569001] cx231xx: probe of 3-1.2:1.1 failed with error -22

Likely a regession since Commit 9d6d20e652c0
("media: v4l2-mc: switch it to use the new approach to setup pipelines")
(v4.19-rc1-100-g9d6d20e652c0), which introduced the use of
PAD_SIGNAL_DV within v4l2_mc_create_media_graph().

This also modifies cx25840 to remove the VBI pad, matching the action
taken in Commit 092a37875a22 ("media: v4l2: remove VBI output pad").

Fixes: 9d6d20e652c0 ("media: v4l2-mc: switch it to use the new approach to setup pipelines")
