Most of the time boards don't enable DM_DEVICE_REMOVE to save code size. We certainly don't unbind devices. A memory leak implies some sort of problem, but if we are booting the OS, all the memory is 'freed' by that process. What problem are you solving here? It is missing from your commit. Regards, Simon
