SubjectRe: [PATCH v1 2/2] i2c: i2c-stm32f7: SYSCFG Fast Mode Plus support for I2C STM32F7
Hi Pierre-Yves,

I love your patch! Yet something to improve:

[auto build test ERROR on wsa/i2c/for-next]
[also build test ERROR on v4.20-rc2 next-20181116]
[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/Pierre-Yves-MORDRET/SYSCFG-Fast-Mode-Plus-support-for-I2C-STM32F7/20181118-135056
base: https://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/for-next
config: xtensa-allmodconfig (attached as .config)
compiler: xtensa-linux-gcc (GCC) 8.1.0
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=8.1.0 make.cross ARCH=xtensa

All errors (new ones prefixed by >>):
