From 6dff5add089f2cedd597937a3e39a01ebba8b7c8 Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Fri, 27 Jul 2018 16:36:29 +0800 Subject: [PATCH] net: usb: pegasus: Replace mdelay() with msleep() in setup_pegasus_II() setup_pegasus_II() 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.
