SubjectRe: [PATCH v2 03/10] pinctrl: axp209: use drv_data of pinctrl_pin_desc to store pin reg
Hi Quentin,

[auto build test WARNING on ]

url: https://github.com/0day-ci/linux/commits/Quentin-Schulz/add-pinmuxing-support-for-pins-in-AXP209-and-AXP813-PMICs/20170929-162846
base:
config: arm64-allmodconfig (attached as .config)
compiler: aarch64-linux-gnu-gcc (Debian 6.1.1-9) 6.1.1 20160705
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
make.cross ARCH=arm64

All warnings (new ones prefixed by >>):
