Hi Bob,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on drm-intel/for-linux-next]
[also build test ERROR on next-20181107]
[cannot apply to v4.20-rc1]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

base: git://anongit.freedesktop.org/drm-intel for-linux-next
config: x86_64-allmodconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-1) 7.3.0
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64

All errors (new ones prefixed by >>):
