Subject: [PATCH] sfc: use swap() to make code cleaner
Date: Thu,  4 Nov 2021 14:53:50 +0800	[thread overview]
Message-ID: <20211104065350.1834911-1-yang.guang5@zte.com.cn> (raw)

From: Yang Guang <yang.guang5@zte.com.cn>

Use the macro 'swap()' defined in 'include/linux/minmax.h' to avoid
opencoding it.
