[PATCH 1/5] PCI: dwc: ep: Remove dw_pcie_ep_init_notify() wrapper
From: Manivannan Sadhasivam
Date: Thu Jun 06 2024 - 03:27:47 EST
Currently dw_pcie_ep_init_notify() wrapper just calls pci_epc_init_notify()
directly. So this wrapper provides no benefit to the glue drivers.
So let's remove it and call pci_epc_init_notify() directly from glue
drivers.
