From e58650b57ee0078ac8986650febeb55263f9ebdf Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Fri, 27 Jul 2018 11:29:56 -0700 Subject: Input: wdt87xx_i2c - replace mdelay() with msleep() in wdt87xx_resume() wdt87xx_resume() 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.
