From: Mark Brown <broonie@xxxxxxxxxx> [ Upstream commit 698813ba8c580efb356ace8dbf55f61dac6063a8 ] For _sx controls the semantics of the max field is not the usual one, max is the number of steps rather than the maximum value. This means that our check in snd_soc_put_volsw_sx() needs to just check against the maximum value.
