Hi Eric,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on net-next/master]

config: sh-rsk7269_defconfig (attached as .config)
compiler: sh4-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
wget -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=sh

All errors (new ones prefixed by >>):
