Subject: [PATCH] net: phy: marvell: Replace mdelay() with msleep() in m88e1116r_config_init()
Date: Fri, 27 Jul 2018 16:34:25 +0800 [thread overview]
Message-ID: <20180727083425.14481-1-baijiaju1990@gmail.com> (raw)
m88e1116r_config_init() 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.
