[PATCH 4/6] backport: add include ftrace_event.h back to backport-4.0.c

From: Luca Coelho <[email protected]>

At least one function, namely ftrace_print_array_seq(), still needs
the ftrace_event.h header file, otherwise sparse may warning that it
is declared as non-static without pre-declaration.
