Subject: [PATCH 0/3] PCI: Locking related improvements

Hi all,

Here are a few locking related coding quality improvements, none of
them aims to introduce any function changes. First two convert "must be
asserted" comments into lockdep asserts for easier detection of
violations. The last patch consolidates almost duplicated code in the
bus/slot locking function.

This series based is based on top of the fix (the last change would
obviously conflict with it):

Ilpo Järvinen (3):
  PCI: Use lockdep_assert_held(pci_bus_sem) to verify lock is held
  PCI: Use device_lock_assert() to verify device lock is held
  PCI: Consolidate pci_bus/slot_lock/unlock/trylock()
