Well, if you are going that far, why not register the notifier from coresight-core ?
I have thought this but gave up.
When register a panic's notifier, it does not provide an argument for passing a private data. So the code below uses container_of() to convert notifier block pointer to the TMC driver data, as a result, the code is specific to TMC driver.
notifier_block in csdev ?
csdev is a common structure, some devices may never use the notifier.
This is the reason I thought it is fine to put notifier into TMC's driver data, as this can meet current requirement perfectly.
