From 2f2debb5a162ea9aeb03ad2532827631e3a68b1a Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Sat, 4 Aug 2018 08:33:44 +0800 Subject: [PATCH] gpu: drm: radeon: si: Replace mdelay() with msleep() in si_pcie_gen3_enable() si_pcie_gen3_enable() is never called in atomic context. It calls mdelay() to busily wait, which is not necessary. mdelay() can be replaced with msleep().
