Subject: [PATCH net-next 4/4] net: hns3: clear hns unused parameter alarm

From: Hao Lan <[email-masked]>
Date: Mon, 15 May 2023 21:46:43 +0800

From: Peiyang Wang <[email-masked]>

Several functions in the hns3 driver have unused parameters.
The compiler will warn about them when building
with -Wunused-parameter option of hns3.
