This one adds some new build warnings:

Documentation/translations/zh_CN/PCI/pci:98: ./include/linux/pci.h:3: WARNING: Duplicate C declaration, also defined at PCI/pci:3.
Declaration is '.. c:struct:: pci_driver'. [duplicate_declaration.c]
kernel/Documentation/translations/zh_CN/PCI/pci:106: ./include/linux/device-id/pci.h:3: WARNING: Duplicate C declaration, also defined at PCI/pci:3.
