SubjectRe: [RFC PATCH v3 4/4] drm/armada: Convert the probe function to the generic drm_of_component_probe()
Hi Liviu,

[auto build test WARNING on drm/drm-next -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

url: https://github.com/0day-ci/linux/commits/Liviu-Dudau/drm-Introduce-generic-probe-function-for-component-based-masters/20151019-231229
config: arm-allmodconfig (attached as .config)
reproduce:
wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=arm

All warnings (new ones prefixed by >>):
