I won't mix them, depending on circumstance, see below.

I assume playlist->name was allocated by libmtp before?

This won't be a problem if you deallocate the structure and its content
yourself (even then it looks strange).

If the library frees the allocated playlist structure, this is right.

I would prefer the later one. The first one can easily lead to errors,
especially if the glib allocators don't use libc malloc implementation
sometime.
