Subject: [PATCH] kconfig: fix savedefconfig for tristate choices
savedefconfig failed to save choice symbols equal to 'y'
for tristate choices.
This resulted in this value being lost.
In particular is fixes an issue where
make ARCH=avr32 atngw100_defconfig
make ARCH=avr32 savedefconfig
cp defconfig arch/avr32/configs/atngw100_defconfig
make ARCH=avr32 atngw100_defconfig
diff -u .config .config.old
failed to produce an identical .config.
