Subject: [PATCH for review] [8/48] i386: Remove unneeded test of 'task' in dump_trace()


From: Jesper Juhl <jesper.juhl@...il.com>

Remove unneeded test of task != NULL from
arch/i386/kernel/traps.c::dump_trace()

At the start of the function we have this test:
        if (!task)
                task = current;
so further down there's no need to test 'task'.
