From 2b81ec69144de93f29fa258d3435557a5773ffb5 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 9 Mar 2012 00:59:46 +0800 Subject: ASoC: fsl: check property 'compatible' for the machine name Check /compatible rather than /model to determine the machine name. The p1022ds older device trees get a different /model from the new ones, while /compatible is consistent there, so checking /compatible will save the bother of detecting older p1022ds device trees.
