From 40a9960b046290939b56ce8e51f365258f27f264 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 30 Sep 2017 11:13:28 +0300 Subject: [PATCH] drm/amdgpu: potential uninitialized variable in amdgpu_vce_ring_parse_cs() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We shifted some code around in commit 9cca0b8e5df0 ("drm/amdgpu: move amdgpu_cs_sysvm_access_required into find_mapping") and now my static checker complains that "r" might not be initialized at the end of the function. I've reviewed the code, and that seems possible, but it's also possible I may have missed something.
