Asking just to make sure it was not me who made a mistake while merging the code.

Asking just > to make sure it was not me who made a mistake while merging the code. My apologies. I wasn't compiling the driver as a module (instead built into the kernel image) BTW, I see ERROR: modpost: "dw_pcie_ep_init" [drivers/pci/controller/dwc/pcie-tegra194.ko] undefined! also along with the above three. So I think even dw_pcie_ep_init() needs to be exported.
