[PATCH 5.4 56/67] net: thunderx: Fix missing destroy_workqueue of nicvf_rx_mode_wq

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yongqiang Liu <liuyongqiang13@xxxxxxxxxx>

[ Upstream commit 42330a32933fb42180c52022804dcf09f47a2f99 ]

The nicvf_probe() won't destroy workqueue when register_netdev()
failed. Add destroy_workqueue err handle case to fix this issue.

Fixes: 2ecbe4f4a027 ("net: thunderx: replace global nicvf_rx_mode_wq work queue for all VFs to private for each of them.")
