From fa1a25c51d02f153b49444aa872bee9da3c13ecf Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 29 Sep 2021 20:15:06 +0200 Subject: [PATCH] PCI: PM: Do not call platform_pci_power_manageable() unnecessarily Drop two invocations of platform_pci_power_manageable() that are not necessary, because the functions called when it returns 'true' do the requisite "power manageable" checks themselves.
