This commit has no upstream equivalent.
After commit 012dba0ab814 ("PCI: keystone: Don't discard .probe()
callback") in 5.4.262, 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().
Fixes: 012dba0ab814 ("PCI: keystone: Don't discard .probe() callback")
