From: Rafael J. Wysocki Date: Wed, 7 Jan 2009 12:12:22 +0000 (+0100) Subject: PCI PM: Put PM callbacks in the order of execution X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f6dc1e5e3d4b523e1616b43beddb04e4fb1d376a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git PCI PM: Put PM callbacks in the order of execution Put PM callbacks in drivers/pci/pci-driver.c in the order in which they are executed which makes it much easier to follow the code. No functional changes should result from this. Signed-off-by: Rafael J.
