fgraph: Change the name of cpuhp state to "fgraph:online"

[PATCH] fgraph: Change the name of cpuhp state to "fgraph:online"

Posted by Steven Rostedt 1 month ago

From: Steven Rostedt <rostedt@goodmis.org>

The cpuhp state name given to cpuhp_setup_state() is "fgraph_idle_init"
which doesn't really conform to the names that are used for cpu hotplug
setups. Instead rename it to "fgraph:online" to be in line with other
states.

Looks good to me.
