A comment for the future, no need to change anything in this patch:

So how should we handle tracing? We would want to provide same
information through logging trace events, right?

One idea I had is that we modify the tracing logging macros to take
struct ath10k (or struct device) and use dev_driver_string() &
dev_name() to provide the same info via trace events.
