    tracing: Move a printk out of ftrace_raw_reg_event_foo() · 3b8e4273
    Li Zefan authored
    Move the printk from each ftrace_raw_reg_event_foo() to
    its caller ftrace_event_enable_disable(). This avoids each
    regfunc trace event callbacks to handle a same error report
    that can be carried from the caller.
    See how much space this saves:
       text    data     bss     dec     hex filename
