In the Linux kernel, the following vulnerability has been resolved:
dma-direct: return struct page from dma_direct_alloc_from_pool()
Commit 5b138c534fda ('dma-direct: factor out a dma_direct_alloc_from_pool
helper') changed dma_direct_alloc_from_pool() to return the CPU address
from dma_alloc_from_pool(). That fits dma_direct_alloc(), but
dma_direct_alloc_pages() also uses the helper and expects a struct page *.
Fix this by making dma_direct_alloc_from_pool() return the struct page *
again, and pass the CPU address back through an out-parameter for the
dma_direct_alloc() caller.
