Current code uses asmlinkage for functions without arguments. This adds an implicit regparm(0) which creates a warning when assigning the function to pointers. Use __visible for the functions without arguments. This avoids having to add regparm(0) to function pointers. Since they have no arguments it does not make any difference.
