of the probe function. So obviously, it is supposed that the DMA driver somehow gets probed before the PSC driver, but I can't see where this is enforced. AFAIK, the order is fairly random, so it could be the other way around.... and indeed, in my case it is.
The order the device model devices get probed in is entirely random and any driver which is relying on this is buggy.
2.- Simply turning the dev_get/set_drvdata and chip initialization order around does work in my case, but doesn't seem a robust solution to me. Any idea how this should be handled?
I'd expect that delaying whatever relies on both devices being there until the ASoC level probes happen is the way forward - you're guaranteed that both deivces will be present there and the probe ordering is guaranteed stable.
