PCI: Fix build if quirks are not enabled
After commit b9c3b266411d27f1a6466c19d146d08db576bfea ("PCI: support device-specific reset methods") the kernel build is broken if CONFIG_PCI_QUIRKS is unset. Fix this by moving pci_dev_specific_reset() to drivers/pci/quirks.c and providing an empty replacement for !CONFIG_PCI_QUIRKS builds. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
