There should be no loss of functionality and no new features, just less and simpler code. Patch [9/9] collects TODOs for hotplug drivers to spur contributions. I've assumed that my patch "PCI: pciehp: Differentiate between surprise and safe removal" (submitted July 31) gets merged before this series: https://patchwork.ozlabs.org/patch/951386/ If that patch is not accepted or other pciehp-related patches are merged before this series, I'll have to rebase patch [4/9] ("PCI: pciehp: Unify controller and slot structs"). No big deal, just a heads-up. Thanks, Lukas Lukas Wunner (9): PCI: Simplify disconnected marking PCI: pciehp: Drop unnecessary includes PCI: pciehp: Drop hotplug_slot_ops wrappers PCI: pciehp: Unify controller and slot structs PCI: pciehp: Reshuffle controller struct for clarity PCI: hotplug: Constify hotplug_slot_ops PCI: hotplug: Drop hotplug_slot_info PCI: hotplug: Embed hotplug_slot PCI: hotplug: Document TODOs arch/powerpc/include/asm/pnv-pci.h | 2 +- drivers/pci/hotplug/TODO | 74 +++++++ drivers/pci/hotplug/acpiphp.h | 10 +- drivers/pci/hotplug/acpiphp_core.c | 36 +--- drivers/pci/hotplug/acpiphp_ibm.c | 2 +- drivers/pci/hotplug/cpci_hotplug.h | 11 +- drivers/pci/hotplug/cpci_hotplug_core.c | 105 +++------- drivers/pci/hotplug/cpci_hotplug_pci.c | 6 +- drivers/pci/hotplug/cpqphp.h | 9 +- drivers/pci/hotplug/cpqphp_core.c | 59 ++---- drivers/pci/hotplug/cpqphp_ctrl.c | 31 +-- drivers/pci/hotplug/ibmphp.h | 9 +- drivers/pci/hotplug/ibmphp_core.c | 121 ++++------- drivers/pci/hotplug/ibmphp_ebda.c | 70 +------ drivers/pci/hotplug/pci_hotplug_core.c | 53 ++--- drivers/pci/hotplug/pciehp.h | 138 ++++++------- drivers/pci/hotplug/pciehp_core.c | 127 +++--------- drivers/pci/hotplug/pciehp_ctrl.c | 255 +++++++++++------------- drivers/pci/hotplug/pciehp_hpc.c | 127 ++++-------- drivers/pci/hotplug/pciehp_pci.c | 24 +-- drivers/pci/hotplug/pnv_php.c | 35 ++-- drivers/pci/hotplug/rpaphp.h | 10 +- drivers/pci/hotplug/rpaphp_core.c | 20 +- drivers/pci/hotplug/rpaphp_pci.c | 11 +- drivers/pci/hotplug/rpaphp_slot.c | 22 +- drivers/pci/hotplug/s390_pci_hpc.c | 44 ++-- drivers/pci/hotplug/sgi_hotplug.c | 63 +++--- drivers/pci/hotplug/shpchp.h | 8 +- drivers/pci/hotplug/shpchp_core.c | 48 ++--- drivers/pci/hotplug/shpchp_ctrl.c | 21 +- drivers/pci/pci.c | 4 +- drivers/pci/pcie/err.c | 8 +- drivers/pci/slot.c | 2 +- drivers/platform/x86/asus-wmi.c | 39 +--- drivers/platform/x86/eeepc-laptop.c | 43 ++-- include/linux/pci_hotplug.h | 43 +--- 36 files changed, 638 insertions(+), 1052 deletions(-) create mode 100644 drivers/pci/hotplug/TODO Acked-by: Andy Shevchenko
