Hi, This is a critical patch (based on pcie -next branch) to fix build bot failure: This build failure is still present in -next: > arm-allmodconfig > ../drivers/pci/host/pcie-mediatek.c:485:8: error: implicit declaration of function 'pci_register_host_bridge' [-Werror=implicit-function-declaration] and we're at -rc7 now. This is because host/pci-mediatek is a separate branch in pci-tree but we (Lorenzo's patches) merge together. Seems Bjorn didn't response these days, so I need someone help to apply this patch to -next. Hi Arnd and Mark, Do you have better idea to handle this situation? I'm really not sure how to fix it in proper ways. Thanks a lot.
