[PATCH ghak21 V3 1/2] audit: remove path param from link denied function

2018-03-15 Thread Richard Guy Briggs
In commit 45b578fe4c3cade6f4ca1fc934ce199afd857edc
("audit: link denied should not directly generate PATH record")
the need for the struct path *link parameter was removed.
Remove the now useless struct path argument.
