Subject: [PATCH] mm/cma: Drop cma_get_name()

cma_get_name() just returns cma->name without any additional transformation
unlike other helpers such as cma_get_base() and cma_get_size(). This helper
is not worth the additional indirection, and can be dropped after replacing
directly with cma->name in the sole caller __add_cma_heap().
