Steven Rostedt (Google) b6d18ab342 tracing/brcm: Use the new __vstring() helper
Instead of open coding a __dynamic_array() with a fixed length (which
defeats the purpose of the dynamic array in the first place). Use the new
__vstring() helper that will use a va_list and only write enough of the
string into the ring buffer that is needed.
