Merge branch 'pci/misc'
- Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device so dwc3 can claim it instead (Vicki Pfau) - Make pci_assign_unassigned_resources() non-init because sparc uses it after init-time (Randy Dunlap) - Remove logic_outb(), _outw(), outl() duplicate declarations (John Sanpe) - Remove unnecessary UTF-8 in Kconfig help text that confuses menuconfig (Liu Song) - Fix double free in __pci_epc_create() (Dan Carpenter) - Simplify pcie_capability_clear_and_set_word() cases that could be pcie_capability_clear_word() (Ilpo Järvinen) * pci/misc: PCI: Simplify pcie_capability_clear_and_set_word() to ..._clear_word() PCI: endpoint: Fix double free in __pci_epc_create() PCI: Replace unnecessary UTF-8 in Kconfig logic_pio: Remove logic_outb(), _outw(), outl() duplicate declarations PCI: Make pci_assign_unassigned_resources() non-init PCI: Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device
