Merge tag 'fixes-non-critical-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC non-critical bug fixes from Arnd Bergmann: "Lots of isolated bug fixes that were not found to be important enough to be submitted before the merge window or backported into stable kernels. The vast majority of these came out of Arnd's randconfig testing and just prevents running into build-time bugs in configurations that we do not care about in practice" * tag 'fixes-non-critical-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (75 commits) ARM: at91: fix a typo ARM: moxart: fix CPU selection ARM: tegra: fix board DT pinmux setup ARM: nspire: Fix compiler warning IXP4xx: Fix DMA masks. Revert "ARM: ixp4xx: Make dma_set_coherent_mask common, correct implementation" IXP4xx: Fix Goramo Multilink GPIO conversion.
