[ Upstream commit f8da001ae7af0abd9f6250c02c01a1121074ca60 ]
The audio graph card doesn't mark its subnodes such as multi {}, dpcm {} and c2c {} as not requiring any suppliers. This causes a hang as Linux waits for these phantom suppliers to show up on boot. Make it clear these nodes have no suppliers.
Example error message: [ 15.208558] platform 2034000.i2s: deferred probe pending: platform: wait for supplier /sound/multi [ 15.208584] platform sound: deferred probe pending: asoc-audio-graph-card2: parse error
