dma: contiguous: Export dev_get_cma_area()

mripard · mszyprow · commit 6207948f389e · 2026-03-31T13:27:20.000+02:00
The CMA dma-buf heap uses the dev_get_cma_area() function to retrieve the default contiguous area. Now that this function is no longer inlined, and since we want to turn the CMA heap into a module, let's export it.
