    Subject[PATCH 1/2] ftrace: Correct a text align for event format output
    If we cat debugfs/tracing/events/ftrace/bprint/format, we'll see:
    name: bprint
    ID: 6
    format:
    field:unsigned char common_type; offset:0; size:1;
    field:unsigned char common_flags; offset:1; size:1;
    field:unsigned char common_preempt_count; offset:2; size:1;
    field:int common_pid; offset:4; size:4;
    field:int common_tgid; offset:8; size:4;

    field:unsigned long ip; offset:12; size:4;
    field:char * fmt; offset:16; size:4;
    field: char buf; offset:20; size:0;

    print fmt: "%08lx (%d) fmt:%p %s"

    There is a redundant blank before char buf, and it need to be deleted.
