    Subject[PATCH 5.17 730/772] ASoC: rt5514: Fix event generation for "DSP Voice Wake Up" control
    Date
    From: Mark Brown <broonie@kernel.org>

    commit 4213ff556740bb45e2d9ff0f50d056c4e7dd0921 upstream.

    The driver has a custom put function for "DSP Voice Wake Up" which does
    not generate event notifications on change, instead returning 0. Since we
    already exit early in the case that there is no change this can be fixed
    by unconditionally returning 1 at the end of the function.
