From 106b8863069e0fb31468ddd6ffcd162cc8430280 Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Sun, 24 Dec 2017 18:39:40 +0800 Subject: [PATCH] i40iw: Replace mdelay with msleep in i40iw_wait_pe_ready i40iw_wait_pe_ready is not called in an interrupt handler nor holding a spinlock. The function mdelay in it can be replaced with msleep, to reduce busy wait.
