From 7c3e1ec1f772c1f740fce3180bf419018582977f Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 5 Feb 2016 17:09:52 -0200 Subject: [media] v4l2-async: call registered_async after subdev registration V4L2 sub-devices might need to do initialization that depends on being registered with a V4L2 device. As an example, sub-devices with Media Controller support may need to register entities and create pad links. Execute the registered_async callback after the sub-device has been registered with the V4L2 device so the driver can do any needed init.
