Dear all, I've difficulty using the name prefix in component, so I want to ask for help. The purpose of using the 'name_prefix' is to put i2c driver name before kcontrol's name. As you all know, the name of the registered kcontrol is defined const, so I couldn't modify direct. So I've thought of some ways, but I don't know which one is good. First, as mentioned above, the name value was take from the struct of driver(snd_soc_component_driver) and the value was added to the name_prefix among the members of the snd_soc_component. Then, the error occurred on the dapm widgets and route. ASoC: no source widget found for CLK_SUPPLY ASoC: Failed to add route CLK_SUPPLY -> direct -> DAC I've registered the 'CLK_SUPPLY' on snd_soc_dapm_widget using macro(SND_SOC_DAPM_SUPPLY). However, with the addition of the name_prefix, the registered widget could not be found. Is thee a way to change the name of kcontrol or dapm widget? or the way use the name_prefix, or an example code? Thanks.
