Hi Olliver,

[auto build test WARNING on pwm/for-next -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

config: avr32-atstk1006_defconfig (attached as .config)
reproduce:
wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=avr32
