SubjectRe: [PATCH 5/6 v2] bus: fsl-mc: supoprt dma configure for devices on fsl-mc bus
Hi Nipun,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on linus/master]
[also build test ERROR on v4.17-rc2 next-20180424]
[cannot apply to iommu/next glikely/devicetree/next]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Nipun-Gupta/Support-for-fsl-mc-bus-and-its-devices-in-SMMU/20180418-034931
config: powerpc64-allmodconfig (attached as .config)
compiler: powerpc64-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=powerpc64
