From d9a7ed770f9d06b998172e4e71791c81476de88f Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 22 Jul 2016 17:17:48 +0200 Subject: [PATCH] drm/etnaviv: Optimize error handling in etnaviv_gem_new_userptr() Refactor this function implementation so that the drm_gem_object_unreference_unlocked() function will only be called once in case of a failure according to the Linux coding style recommendation for centralized exiting of functions.
