+Subject: [PATCH] staging: vchiq_arm: Fix platform device
+ unregistration
+
+In error case platform_device_register_data would return an ERR_PTR
+instead of NULL. So we better check this before unregistration.
+
+Fixes: 37b7b3087a2f ("staging/vc04_services: Register a platform device for the camera driver.")
