[PATCH 4/5] PCI: qcom-ep: Use the generic dw_pcie_ep_linkdown() API to handle Link Down event

From: Manivannan Sadhasivam
Date: Thu Jun 06 2024 - 03:28:44 EST


Now that the API is available, let's make use of it. It also handles the
reinitialization of DWC non-sticky registers in addition to sending the
notification to EPF drivers.
