Subject: [PATCH v2] net: microchip: sparx5: Fix missing destroy_workqueue of mact_queue
Date:   Sat, 3 Dec 2022 15:02:59 +0800
Message-ID: <20221203070259.19560-1-linqiheng@huawei.com>

Precedence: bulk

The mchp_sparx5_probe() won't destroy workqueue created by
create_singlethread_workqueue() in sparx5_start() when later
inits failed. Add destroy_workqueue in the cleanup_ports case,
also add it in mchp_sparx5_remove()

Fixes: b37a1bae742f ("net: sparx5: add mactable support")
