Opening an SPE event shows a warning that doesn't concern the user: $ perf record -e arm_spe Unknown/empty format name: discard Perf only wants to know if the discard bit is set for configuring the event, not in response to anything the user has done. Fix it by adding another helper that returns if a config bit exists without warning. We should probably keep the warning in evsel__get_config_val() to avoid having every caller having to do it, and most format bits should never be missing. Add a test for the new helper. Rename the parent test function to be more generic rather than adding a new one as it requires a lot of boilerplate.
