I found this odd also, but looking in Documentation/sound/alsa/DocBook/writing-an-alsa-driver I found that the sense of the test is indeed the reverse of what you would expect -- you are specifying the condition that *should* be met, and the action to take if it is not. I can also verify that the substream pointer is indeed null -- the reason I enabled alsa debugging in the first place is that the kernel was crashing due to a null pointer :-) Steve -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
