From d6aa37cd04fdafaf31ae89691e537535df43ca78 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 5 Nov 2019 11:30:36 +0100 Subject: PCI/PM: Avoid exporting __pci_complete_power_transition() Notice that radeon_set_suspend(), which is the only caller of __pci_complete_power_transition() outside of pci.c, really only cares about the pci_platform_power_transition() invoked by it, so export the latter instead of it, update the radeon driver to call pci_platform_power_transition() directly and make __pci_complete_power_transition() static. Code rearrangement, no intentional functional impact. Link: https://lore.kernel.org/r/1731661.ykamz2Tiuf@kreacher Signed-off-by: Rafael J.
