tracing/ftrace: adapt mmiotrace to the new type of print_line
Adapt mmiotrace to the new print_line type. By default, it ignores (and consumes) types it doesn't support. Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Acked-by: Pekka Paalanen <pq@iki.fi> Signed-off-by: Ingo Molnar <mingo@elte.hu>
