There are several things the patch adding the support for 'I2S Reference' got wrong: - "None" selection is in fact equals to last selected reference - The custom put overrides RX/TX len, TDM slot sizes, etc - the enum is useless in most part for the reference tracking - there is no need for EXT control as there is a single bit in RT1011_TDM1_SET_1 register (bit 7) which selects the reference - it was using ucontrol->value.integer.value[0] in the put/get callbacks which causesed access to 'I2S Reference' enum with alsamixer to fail Complements: c3de683c4d1d ("ASoC: rt1011: Fix 'I2S Reference' enum control caused error") Signed-off-by: Peter Ujfalusi <peter.ujfalusi@linux.intel.com> --- Hi, Changes since v1: - Rebased on top of next - changed the tag from Fixes to Complements to make sure that the crash fix and the fix for the implementation stays together. This patch is an iteration on https://lore.kernel.org/alsa-devel/20211011144518.2518-1-peter.ujfalusi@linux.intel.com/ to fix 87f40af26c262 ("ASoC: rt1011: add i2s reference control for rt1011"). In essence it is reverting the original patch to use SOC_ENUM_SINGLE_DECL/SOC_ENUM to handle the bit to select the I2S reference.
