[PATCH v2 0/2] ASoC: wm_adsp: Report when a control write changes the value

Writing a firmware control should be returning 1 if the control value
changed, so these two patches add that.

Though this is an ALSA requirement it is also useful for non-ALSA clients
of cs_dsp to know if the control value changed, so the main handling is
implemented in cs_dsp. TLV controls are specifically an ALSA thing so they
are handled specially in wm_adsp.

Simon Trimmer (2):
firmware: cs_dsp: cs_dsp_coeff_write_ctrl() should report changed
ASoC: wm_adsp: Return whether changed when writing controls
