[alsa-devel] asoc multi-component: almost there!

[Timur Tabi]

Is the machine driver required to run last?  The reason I ask is that
my DMA driver is currently initialized via arch_initcall().  If I
change that to module_init(), ASOC fails to register any sound cards.

Here's the debug output with arch_initcall():
