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 causes access to 'I2S Reference' enum with alsamixer to fail: $ alsamixer cannot load mixer controls: Invalid argument

cml_rt1011_rt5682 cml_rt1011_rt5682: control 2:0:0:TL I2S Reference:0: access overflow

It should have used ucontrol->value.enumerated.item[0], but since there is no need for the custom code, it does not really matter.

Fixes: 87f40af26c262 ("ASoC: rt1011: add i2s reference control for rt1011") Reported-by: Seppo Ingalsuo seppo.ingalsuo@linux.intel.com Signed-off-by: Peter Ujfalusi peter.ujfalusi@linux.intel.com --- Hi,

This patch is an iteration on https://lore.kernel.org/alsa-devel/20211011144518.2518-1-peter.ujfalusi@linu...

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.

Regards, Peter
