[PATCH 0/7] ASoC: SOF: start using tracing instead of dev_dbg

[Pierre-Louis Bossart]

Multiple maintainers have told us to start using the tracing
subsystem. Wish granted, this patchset suggested by Noah Klayman
removes a number of verbose and arguably useless dev_dbg or dev_vdbg
logs.

Beyond higher efficiency and less intrusive instrumentation, the use
of bpftrace scripts bring new functionality and helps gather
statistics on usage count on a running system, see how we can get
information on suspend/resume times with [1]
