Currently platforms/drivers needing to get the machine model name are

counting is either missing or incorrect.
This patch adds support to read the machine model name either using
the "model" or the "compatible" property in the device tree root node.

I like the idea. One small comment:
Thanks. I prefer it as single patch but it can't be applied to any tree.
Any suggestions on handling this patch to fix the warning in -next ?
+int of_machine_get_model_name(const char **model)
+{
+ int error;
+ struct device_node *root;
+
+ root = of_find_node_by_path("/");
+ if (!root)
+ return -EINVAL;
The global of_root variable points ot this already, and is defined
in the same file, so I think we can just skip the lookup.
Ah right, will fix it.
