Function tcf_action_dump_1() is not used outside of act_api.c, so remove
the superfluous EXPORT_SYMBOL() and marks it static.

You shouldnt have so many line changes to remove the EXPORT and change
"int" to "static int".
What am i missing?
Unnecessary line changes add extra effort to git archeology
cheers,

Hi Jamal，
Thank you for your reply. Maybe just declare function in the file
without moving the line number?
