I tried to look for his reasons, if any, but even in earliest posted versions use devm* for allocating memory I guess this is one of examples of devm* usage in wrong context. Given that you, as you have to, because this is not a device driver, manually freeing that memory with devm_kfree(), the only thing that devm_kzalloc and friends buy you here is extra memory allocations for devres structures and few extra cycles for maintaining them.
