Hi Douglas,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on v5.0-rc2]
[also build test ERROR on next-20190116]
[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/Douglas-Anderson/drm-msm-Fix-A6XX-support-for-opp-level/20190118-042538
config: arm-imx_v6_v7_defconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 8.2.0-11) 8.2.0
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
GCC_VERSION=8.2.0 make.cross ARCH=arm
