From c51cebb890dc76260c02354882cf333c8207dd19 Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Sat, 4 Aug 2018 08:25:35 +0800 Subject: [PATCH] gpu: drm: radeon: cik: Replace mdelay() with msleep() in cik_pcie_gen3_enable() cik_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(). This is found by a static analysis tool named DCNS written by myself.
