Subject: [media] v4l: vsp1: Register pipe with output WPF

From: Kieran Bingham <[email protected]>

[ Upstream commit 1531a208ed861e4bd287444f9466ffcf98383de2 ]

The DRM object does not register the pipe with the WPF object. This is used internally throughout the driver as a means of accessing the pipe. As such this breaks operations which require access to the pipe from WPF interrupts.

Register the pipe inside the WPF object after it has been declared as the output.
