Merge branch 'fixes_for_linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull CMA and DMA-mapping fixes from Marek Szyprowski:
"This consists mainly of a set of one-liner fixes and cleanups for a
few minor issues identified in both Contiguous Memory Allocator code
and ARM DMA-mapping subsystem."
* 'fixes_for_linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
ARM: mm: Remove unused arm_vmregion priv field
ARM: dma-mapping: fix build warning in __dma_alloc()
ARM: dma-mapping: support debug_dma_mapping_error
mm: cma: alloc_contig_range: return early for err path
drivers: cma: Fix wrong CMA selected region size default value
drivers: dma-coherent: Fix typo in dma_mmap_from_coherent documentation
drivers: dma-contiguous: Don't redefine SZ_1M
