Subject[PATCH AUTOSEL 5.19 064/105] drm/amdgpu: Fix one list corruption when create queue fails
Date
From: xinhui pan <xinhui.pan@amd.com>

[ Upstream commit cc3cb791f19ad0c4f951f38c98aa513b042ab329 ]

Queue would be freed when create_queue_cpsch fails
So lets do queue cleanup otherwise various list and memory issues
happen.
