SubjectRe: [PATCH v7 3/5] venus: firmware: register separate platform_device for firmware loader
Hi Stanimir,

I love your patch! Yet something to improve:

[auto build test ERROR on linuxtv-media/master]
[also build test ERROR on v4.19-rc3 next-20180913]
[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/Vikash-Garodia/Venus-updates-PIL/20180915-165454
base: git://linuxtv.org/media_tree.git master
config: arm-allyesconfig (attached as .config)
compiler: arm-linux-gnueabi-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
GCC_VERSION=7.2.0 make.cross ARCH=arm

All errors (new ones prefixed by >>):
