Subject: [PATCH] drm/amdgpu: fix parser init error path to avoid crash in
 parser fini
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ Upstream commit 607523d19c9d67ba4cf7bdaced644f11ed04992c ]

If we don't reset the chunk info in the error path, the subsequent
fini path will double free.
