Subject: [PATCH 6.6 363/638] media: cadence: csi2rx: use match fwnode for media link

From: Julien Massot <julien.massot@...labora.com>

[ Upstream commit 448699c522af9e3266f168c3f51f4c3713c7bee1 ]

Since commit 1029939b3782 ("media: v4l: async: Simplify async sub-device fwnode matching"),
async connections are matched using the async sub-device fwnode, not that
of the endpoint. Fix this by using the fwnode of the connection match to
find the pad.
