We have HNAE interfacing layer above HCLGE, if any such out-of-tree code maintains the sanctity of that interface then there should not be an issue at HCLGE. These functions are never going to get directly used by such out-of-tree code.

I was wondering if we could detect below condition in the Makefile itself and not depend upon separate namespace? "With CONFIG_HNS3_HCLGE=y and CONFIG_HNS3_HCLGEVF=m " Thanks Salil.

With CONFIG_HNS3_HCLGE=y and CONFIG_HNS3_HCLGEVF=m, objects from hns3/hns3_common are linked into a module and into vmlinux even though the expected CFLAGS are different between builtins and modules. This is the same situation as fixed by commit 637a642f5ca5 ("zstd: Fixing mixed module-builtin objects"). There's also no need to duplicate such big piece of object code into two modules. Introduce the new module, hclge_common, to provide the common functions to both hclge and hclgevf.
