SubjectRe: [PATCH 2/2] mtd: rawnand: meson: add support for Amlogic NAND flash controller
Hi Liang,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on mtd/nand/next]
[also build test ERROR on v4.17 next-20180613]
[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/Yixun-Lan/mtd-rawnand-meson-add-Amlogic-NAND-driver-support/20180613-161917
base: git://git.infradead.org/linux-mtd.git nand/next
config: sparc64-allyesconfig (attached as .config)
compiler: sparc64-linux-gnu-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=sparc64
