From 563476ae0c5e48a028cbfa38fa9d2fc0418eb88f Mon Sep 17 00:00:00 2001 From: Shay Drory Date: Sun, 11 Apr 2021 15:32:55 +0300 Subject: net/mlx5: Synchronize correct IRQ when destroying CQ The CQ destroy is performed based on the IRQ number that is stored in cq->irqn. That number wasn't set explicitly during CQ creation and as expected some of the API users of mlx5_core_create_cq() forgot to update it. This caused to wrong synchronization call of the wrong IRQ with a number 0 instead of the real one. As a fix, set the IRQ number directly in the mlx5_core_create_cq() and update all users accordingly.
