This one is not making sense to me...
In sdma_load_script() what data structure are we protecting at single
threaded init time prior to registering channels?
This sdma_load_context() is called from various ->prep() contexts.
What guarantees are there that we can sleep in these contexts? At
least ->prep_memcpy() might be called in a atomic context. I have
been assuming the same for all prep routines across archs.
