Subject: 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
Git-commit: 40a9960b046290939b56ce8e51f365258f27f264
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
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.
