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) * pci/hotplug: PCI: pciehp: Don't enable HPIE when resuming in poll mode PCI: pciehp: Avoid unnecessary device replacement check PCI/portdrv: Only disable pciehp interrupts early when needed PCI: hotplug: Inline pci_hp_{create,remove}_module_link() PCI: hotplug: Avoid backpointer dereferencing in has_*_file() PCI: hotplug: Drop superfluous NULL pointer checks in has_*_file() PCI: hotplug: Drop superfluous try_module_get() calls PCI: hotplug: Drop superfluous pci_hotplug_slot_list PCI: cpcihp: Remove unused .get_power() and .set_power() PCI: shpchp: Remove 'shpchp_debug' module parameter PCI: shpchp: Remove unused logging wrappers PCI: shpchp: Change dbg() -> ctrl_dbg() PCI: shpchp: Remove logging from module init/exit functions
