Under certain circumstances, such can lead to the situation fixed by commit 637a642f5ca5 ("zstd: Fixing mixed module-builtin objects"). Introduce the new module, intel_skl_int3472_common, to provide the functions from common.o to both discrete and tps68470 drivers. This adds only 3 exports and doesn't provide any changes to the actual code.
