[PATCH net-next 1/5] net: hns3: remove always exist devlink pointer check
From: Leon Romanovsky <leon@kernel.org>
Date: 2021-08-10 13:37:53
Also in:
lkml
Subsystem:
hisilicon network subsystem 3 driver (hns3), hisilicon network subsystem driver, networking drivers, the rest · Maintainers:
Jian Shen, Jijie Shao, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
From: Leon Romanovsky <leonro@nvidia.com>
The devlink pointer always exists after hclge_devlink_init() succeed.
Remove that check together with NULL setting after release and ensure
that devlink_register is last command prior to call to devlink_reload_enable().
Fixes: b741269b2759 ("net: hns3: add support for registering devlink for PF")
