[PATCH v1 2/2] ASoC: sdw_utils: add spk component string for tac5xx2 family

Message-ID <[email protected]>
  The tac5xx2 RTD init does not populate card->components with the
spk:<prefix> string. With this change, "amixer -D hw:<card> info"
includes the spk identifier for each tac5xx2 speaker component,
following the same pattern used by other codec families.

  This allows userspace to identify the speaker codec at runtime
and enables UCM card matching for the tac5xx2 family.
