Sorry? This changelog entry doesn't make sense to me since this patch

is for documentation and not a compiler error.
If you prefer them declared as C code, please try it this way:
+	struct pci_dev dev*;

+	size_t size;

	dma_addr_t dma_handle;
	cpu_addr = pci_alloc_consistent(dev, size, &dma_handle);
and delete the verbage (plain text) that defines the parameters.
If you are confusing "dev" with "struct device *" and want to change

all the references to "pdev", please do the above *and* write something

like the following in the changelog:

	To avoid confusion with struct device, rename ...
thanks!
