Hi all, this series fixes up three mips-specific fbdev drivers to not poke into the return values from the DMA memory allocators, as those aren't guranteed to be pages backed (although on mips in practice they are). Two of them are also fixed up to use the proper DMA API mmap helper. Note that the first patch is required for pending mips DMA changes, so if they are queued up for 5.3 we'll need a stable branch that can be pulled into the dma-mapping or mips tree.
