kernel test robot helped identify this as related to fortify. The error
appeared with commit 54d9469bc515 ("fortify: Add run-time WARN for
cross-field memcpy()")

Resolve this in the same style as commit cfecea6ead5f ("lib/string:
Move helper functions out of string.c")

Fixes: 54d9469bc515 ("fortify: Add run-time WARN for cross-field memcpy()")

not sure about the fixes tag:
compile error only occurs due to the fortify commit, but it looks like
this change could have been part of the other commit identified in the
message: lib/string move helper functions?
