Subject: [PATCH] net: amd-xgbe: add missed tasklet_kill
Date:   Wed, 28 Dec 2022 16:14:47 +0800
Message-Id: <20221228081447.3400369-1-jiguang.xiao@windriver.com>

From: Jiguang Xiao <jiguang.xiao@windriver.com>

The driver does not call tasklet_kill in several places.
Add the calls to fix it.

Fixes: 85b85c853401 (amd-xgbe: Re-issue interrupt if interrupt status
not cleared)
