Are you sure this isn't a bug in the core? -84..40 should be a valid
range for a signed control. See Marek's fix in 9bdd10d57a ("ASoC: ops:
Shift tested values in snd_soc_put_volsw() by +min") though that only
kicks in for systems with a platform_max. I can't immediately spot any
other issues for S8 but I could be missing something.
