(Before I post this as the 'final' patch and CC all the driver developers that
are affected, I'd like to do an RFC post first. I always hated the alloc context
for obfuscating what is really going on, but let's see what others think).
Instead of allocating a struct that contains just a single device pointer,
just pass that device pointer around. This avoids having to check for
memory allocation errors and is much easier to understand since it makes
explicit what was hidden in an opaque handle before.
