    iio: adc: ti-ads1015: don't return invalid value from buffer setup callbacks · a6fe5e52

    pm_runtime_get_sync() and pm_runtime_put_autosuspend() return 0 on
    success, 1 if the device's runtime PM status was already requested status
    or error code on failure.  So a positive return value doesn't indicate an
    error condition.
    
    However, any non-zero return values from buffer preenable and postdisable
    callbacks are recognized as an error and this driver reuses the return
    value from pm_runtime_get_sync() and pm_runtime_put_autosuspend() in
    these callbacks.  This change fixes the false error detections.
