[PATCH 5.15 249/779] drm/bridge: lt9611uxc: Cancel only drivers work

[Greg Kroah-Hartman]

From: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx>

[ Upstream commit dfa687bffc8a4a21ed929c7dececf01b8f1f52ee ]

During device remove care needs to be taken that no work is pending
before it removes the underlying DRM bridge etc, but this can be done on
the specific work rather than waiting for the flush of the system-wide
workqueue.
