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.
