There's already fairly extensive tracepoints for DAPM - this seems to correspond to snd_soc_dapm_widget_power, though it's at the application time rather than the queue time so we could add another tracepoint for this if you like? I can see that the separate tracepoint would be useful, I mostly use the regmap tracepoints for that purpose but not every widget has register I/O. Tracepoints are less noisy for the system as a whole than tracing every DAPM operation in dmesg, that tends to irritate other users if it's left in as standard.
