[PATCH 5.6 022/254] media: imx: imx7_mipi_csis: Power off the source when stopping streaming

[Greg Kroah-Hartman]

From: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>

[ Upstream commit 770cbf89f90b0663499dbb3f03aa81b3322757ec ]

The .s_stream() implementation incorrectly powers on the source when
stopping the stream. Power it off instead.
