The original fix was specifically related to the internal FIFO on the au0828 where it can get shifted by one or more bits (i.e. the leading byte is no longer 0x47 but 0x47 << X). Hence it's an issue unrelated to the actual au8522. I suspect this is actually a different problem which out of dumb luck gets "fixed" by resetting the chip. Without more details on the specific behavior you are seeing though I cannot really advise on what the correct change is. This patch should not be accepted upstream without more discussion.
