6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ivan Vecera <ivecera@xxxxxxxxxx>
[ Upstream commit d3276f928a1d2dfebc41a82e967cd0dffeb540f8 ]
Enum i40e_memory_type enum is unused in i40e_allocate_dma_mem() thus
can be safely removed. Useless macros in i40e_alloc.h can be removed
as well.
