If anyone has any objections, please let me know. ------------------ From: Mark Hills commit c914f55f7cdfafe9d7d5b248751902c7ab57691e upstream. This assertion seems to imply that chip->dsp_code_to_load is a pointer. It's actually an integer handle on the actual firmware, and 0 has no special meaning. The assertion prevents initialisation of a Darla20 card, but would also affect other models. It seems it was introduced in commit dd7b254d.
