    iio: core: Add devm_ APIs for iio_channel_{get,release} · 8bf872d8
    Laxman Dewangan authored
    Some of kernel driver uses the IIO framework to get the sensor
    value via ADC or IIO HW driver. The client driver get iio channel
    by iio_channel_get() and release it by calling iio_channel_release().
    
    Add resource managed version (devm_*) of these APIs so that if client
    calls the devm_iio_channel_get() then it need not to release it explicitly,
    it can be done by managed device framework when driver get un-binded.
    
    This reduces the code in error path and also need of .remove callback in
    some cases.
