[PATCH] powerpc/pci: Enable PCI domains in /proc when PCI bus numbers are not unique

2022-08-20 Thread Pali Rohár
On 32-bit powerpc systems with more PCIe controllers and more PCI domains, where on more PCI domains are same PCI numbers, when kernel is compiled with CONFIG_PROC_FS=y and CONFIG_PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT=y options, kernel prints "proc_dir_entry 'pci/01' already registered" error message.
