Add debug print useful for issue analysis in soc-dapm.
This print for dapm widgets useful for debugging to find
widgets powering up and down.
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.
Thanks Mark for the response. But this is not default err/info print and
only dynamic debug print which should not result in noise. In case of
customer OEMs/final product versions where less options of debugging,
dynamic dmesg logging is preferable provided faster and this print is
used
to identify issues debug fastly sometimes.
