[PATCH] ASoC: adau7118: don't disable regulators on device unbind

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The regulators are supposed to be controlled through the
set_bias_level() component callback. Moreover, the regulators are not
enabled during probe and so, this would lead to a regulator unbalanced
use count.

Fixes: ca514c0f12b02 ("ASOC: Add ADAU7118 8 Channel PDM-to-I2S/TDM Converter driver")

Note this was only checked by code inspection but unless I'm missing
something, it looks clear this could happen by just insmod + rmmod the
module.
