This commit has no upstream equivalent. After commit 012dba0ab814 ("PCI: keystone: Don't discard .probe() callback") in 5.4, there are two modpost warnings when building with clang: WARNING: modpost: vmlinux.o(.text+0x5aa6dc): Section mismatch in reference from the function ks_pcie_probe() to the function .init.text:ks_pcie_add_pcie_port() The function ks_pcie_probe() references the function __init ks_pcie_add_pcie_port(). This is often because ks_pcie_probe lacks a __init annotation or the annotation of ks_pcie_add_pcie_port is wrong. WARNING: modpost: vmlinux.o(.text+0x5aa6f4): Section mismatch in reference from the function ks_pcie_probe() to the function .init.text:ks_pcie_add_pcie_ep() The function ks_pcie_probe() references the function __init ks_pcie_add_pcie_ep(). This is often because ks_pcie_probe lacks a __init annotation or the annotation of ks_pcie_add_pcie_ep is wrong. ks_pcie_add_pcie_ep() was removed in upstream commit a0fd361db8e5 ("PCI: dwc: Move "dbi", "dbi2", and "addr_space" resource setup into common code") and ks_pcie_add_pcie_port() was removed in upstream commit 60f5b73fa0f2 ("PCI: dwc: Remove unnecessary wrappers around dw_pcie_host_init()"), both of which happened before upstream commit 7994db905c0f ("PCI: keystone: Don't discard .probe() callback"). As neither of these removal changes are really suitable for stable, just remove __init from these functions in stable, as it is no longer a correct annotation after dropping __init from ks_pcie_probe().
