Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull one more arm-soc bugfix from Olof Johansson: "Here's a bugfix for orion5x. Without this, PCI doesn't initialize properly because of too small coherent pool to cover the allocations needed. A similar fix has already been done on kirkwood." * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: Orion5x: Fix too small coherent pool.
