From a6c1c6f3547b6c4cbd4a30d67a968ee1519a8ffd Mon Sep 17 00:00:00 2001 From: Shawn Lin Date: Tue, 24 May 2016 17:32:10 +0800 Subject: [PATCH] PCI/ASPM: Remove redundant check of pcie_set_clkpm Without supporting clock PM capable, if we want to disable clkpm, we don't need this extra check as it must already be zero for the enable argument. And it's the same for enabling clkpm here. So let's remove this check.
