Move the DT alias declaration to the I2C shim in the cases +where the shim is enabled. This works around a problem caused by a +4.19 commit [1] that generates DT/OF uevents for I2C drivers. + +2. Fix the diagnostics in an error path of the soundcard driver to +correctly identify the reason for the failure to load. + +3. Move the declaration of the clock node in the overlay outside +the I2C node to avoid warnings. + +4.
