From 7ba7db27d18d141973ad7eaf1f339218d81a31a4 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Sat, 13 Oct 2018 20:51:23 +0200 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.")
