Merge branch 'pci/hotplug'

Merge branch 'pci/hotplug'

- Drop shpchp module init/exit logging (Ilpo Järvinen)

- Replace shpchp dbg() with ctrl_dbg() and remove unused dbg(), err(),
  info(), warn() wrappers (Ilpo Järvinen)

- Drop 'shpchp_debug' module parameter in favor of standard dynamic
  debugging (Ilpo Järvinen)

- Drop unused .get_power(), .set_power() function pointers (Guilherme
  Giacomo Simoes)

- Drop superfluous pci_hotplug_slot_list (Lukas Wunner)

- Drop superfluous try_module_get() calls (Lukas Wunner)

- Drop superfluous NULL pointer checks (Lukas Wunner)

- Pass struct hotplug_slot pointers directly to avoid backpointer
  dereferencing in has_*_file() (Lukas Wunner)

- Inline pci_hp_{create,remove}_module_link() to reduce exported symbols
  (Lukas Wunner)

- Disable hotplug interrupts in portdrv only when pciehp is not enabled to
  prevent issuing two hotplug commands too close together (Feng Tang)

- Skip pciehp 'device replaced' check if the device has been removed to
  address a common deadlock when resuming after a device was removed during
  system sleep (Lukas Wunner)

- Don't enable pciehp hotplug interupt when resuming in poll mode (Ilpo
  Järvinen)
