Subject: [PATCH] net: adaptec: Replace mdelay() with msleep() in starfire_init_one()
Date:   Fri, 27 Jul 2018 11:51:06 +0800
Message-Id: <20180727035106.5185-1-baijiaju1990@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

starfire_init_one() is never called in atomic context.
It calls mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().

This is found by a static analysis tool named DCNS written by myself.
