Hi John,

I love your patch! Perhaps something to improve:

[also build test WARNING on tegra-drm/drm/tegra/for-next linus/master v5.9-rc8]
[cannot apply to next-20201002]

If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <lkp@intel.com>

echo
echo "sparse warnings: (new ones prefixed by >>)"
echo
>> drivers/dma-buf/heaps/system_heap.c:25:17: sparse: sparse: symbol 'sys_uncached_heap' was not declared. Should it be static?

Please review and possibly fold the followup patch.
