From ff3ce480e8b59fbc0f459476fe1b5451464592a5 Mon Sep 17 00:00:00 2001 From: Bogicevic Sasa Date: Sun, 27 Dec 2015 13:21:11 -0800 Subject: PCI: Fix all whitespace issues Fix all whitespace issues (missing or needed whitespace) in all files in drivers/pci. Code is compiled with allyesconfig before and after code changes and objects are recorded and checked with objdiff and they are not changed after this commit.
