The arch/arm/mach-*/ patches usually get picked up by platform maintainers, but not all of them are very active. I would suggest you wait a few more days for individual maintainers to either pick up, ack or nack the patches. For those that you get either an Ack or no reply, please resend them to soc@kernel.org, and I'll apply them to the soc tree directly. Arnd

of_find_compatible_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.
