tracing/fastboot: fix bootgraph.pl initcall name regexp
The regexp used to match the start and the end of an initcall are matching only on [a-zA-Z\_]. This rules out initcalls with a number in them. This patch is fixing that. Signed-off-by: Arnaud Patard <apatard@mandriva.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
