There is no limit on high "idx" can go.  It should be less than
ARRAY_SIZE(data.states) which is 16.

The "data" variable wasn't declared in that scope so I shifted the code
around a bit to make it work.  Also I made "idx" unsigned.

Robin Murphy 539aae6e3a drm/nouveau/Revert "drm/nouveau/device/pci: set as non-CPU-coherent on ARM64" 
This reverts commit 1733a2ad36.

There is apparently something amiss with the way the TTM code handles
DMA buffers, which the above commit was attempting to work around for
arm64 systems with non-coherent PCI. Unfortunately, this completely
breaks systems *with* coherent PCI (which appear to be the majority).

Booting a plain arm64 defconfig + CONFIG_DRM + CONFIG_DRM_NOUVEAU on
a machine with a PCI GPU having coherent dma_map_ops (in this case a
7600GT card plugged into an ARM Juno board) results in a fatal crash:
