What about replacing av_fifo_write() by av_fifo_generic_write() and
providing a wraper (maybe with attribute_deprecated)?
If you now say thats what you are doing then look at your patch, you
dont replace av_fifo_write() you add a new function.
That is you add code duplication with the intent to remove the old code
in a subsequent patch. This hides the changes between the old and new

Consistency is no excuse to leave a problem unsolved.
