Subject: [PATCH v6 15/17] media: qcom: camss: Move vfe_disable into a common routine where applicable
We can move vfe_disable() into a common routine in the core VFE file
provided we make wm_stop() a VFE specific callback.
The callback is required to capture the case where VFE 17x currently isn't
VC enabled where as VFE 480 is.
Suggested-by: Laurent Pinchart <laurent.pinchart@...asonboard.com>
