[lttng-dev] [PATCH lttng-modules 2/6] Fix: asoc: Consolidate path trace events

[Michael Jeanson]

See upstream commit:

  commit 6e588a0d839b51bae49852b68740a25cacc91978
  Author: Lars-Peter Clausen <lars at metafoo.de>

    ASoC: dapm: Consolidate path trace events

    The snd_soc_dapm_input_path and snd_soc_dapm_output_path trace events are
    identical except for the direction. Instead of having two events have a
    single one that has a field that contains the direction.
