[PATCH 1/9] PCI: Remove redundant debug output in pci_do_fixups

From: Myron Stowe
Date: Thu Jun 21 2012 - 16:24:34 EST


When the boot argument 'initcall_debug' is specified, redundant debug
output occurs for each device as a quirk is applied:
...
pci 0000:00:1a.0: calling quirk_usb_early_handoff+0x0/0x620
calling quirk_usb_early_handoff+0x0/0x620 @ 1 for 0000:00:1a.0
pci fixup quirk_usb_early_handoff+0x0/0x620 returned after 32 usecs for 0000:00: 1a.0
...

This patch removes the redundancy by eliminating the first debug output
occurence in the sequence shown above when 'initcall_debug' is specified.
