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. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
