Subject: [PATCH] staging/vc04_services: Register a platform device for the camera driver.
Git-commit: 37b7b3087a2f183325502e8dae7fbb9cf987f221
Patch-mainline: v4.18-rc1
References: FATE#324827

We had the camera driver set up in a module_init function, but that
meant that the camera driver would fail to load if it was initialized
before VCHI.  By attaching to this platform_device, it can get a
defined load order.
