From 70be8b3dab43497718a2260f1daf47d378815d90 Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Tue, 5 Jun 2018 12:05:47 +0000 Subject: drm/i915/guc: Don't leak stage descriptor pool on init failure In case of failure during GuC clients creation, we forget to cleanup earlier pool allocation. Use proper teardown to fix that.
