region only at the granularity of a page. For smaller allocations,

::
void
dma_release_declared_memory(struct device *dev)
Remove the memory region previously declared from the system. This
API performs *no* in-use checking for this region and will return
unconditionally having removed all the required structures. It is the
driver's job to ensure that no parts of this memory region are
currently in use.
