drivers/dma-buf/heaps/cma_heap.c: In function '__add_cma_heap':
drivers/dma-buf/heaps/cma_heap.c:379:28: error: invalid use of undefined type 'struct cma'
  379 |         exp_info.name = cma->name;
      |                            ^~

Fixing this would require moving the `struct cma' definition into
cma.h.  I don't think that's worthwhile.
