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.
