Yeah, I do prefer tracepoint_kernel_find_by_name() to stay consistent
with the other tracepoint functions. But we have
"for_each_kernel_tracepoint()" and not "for_each_tracepoint_kernel()",
thus we need to pick being consistent with one or the other. One answer
is to use tracpoint_kernel_find_by_name() and rename the for_each to
for_each_tracpoint_kernel().
