kconfig: Fix defconfig when one choice menu selects options that another choice menu depends on
The defconfig and Kconfig combination below, which is based on 3.10-rc4 Kconfigs, resulted in several options getting set to "m" instead of "y". defconfig.choice: ---8<--- CONFIG_MODULES=y CONFIG_USB_ZERO=y ---8<--- Kconfig.choice: ---8<--- menuconfig MODULES bool "Enable loadable module support" config CONFIGFS_FS tristate "Userspace-driven configuration filesystem" config OCFS2_FS tristate "OCFS2 file system support" depends on CONFIGFS_FS select CRC32 config USB_LIBCOMPOSITE tristate select CONFIGFS_FS choice tristate "USB Gadget Drivers" default USB_ETH config USB_ZERO tristate "Gadget Zero (DEVELOPMENT)" select USB_LIBCOMPOSITE config USB_ETH tristate "Ethernet Gadget (with CDC Ethernet support)" select USB_LIBCOMPOSITE endchoice config CRC32 tristate "CRC32/CRC32c functions" default y choice prompt "CRC32 implementation" depends on CRC32 default CRC32_SLICEBY8 config CRC32_SLICEBY8 bool "Slice by 8 bytes" endchoice ---8<--- $ scripts/kconfig/conf --defconfig=defconfig.choice Kconfig.choice would result in: .config: ---8<--- CONFIG_MODULES=y CONFIG_CONFIGFS_FS=m CONFIG_USB_LIBCOMPOSITE=m CONFIG_USB_ZERO=m CONFIG_CRC32=y CONFIG_CRC32_SLICEBY8=y ---8<--- when the expected result would be: .config: ---8<--- CONFIG_MODULES=y CONFIG_CONFIGFS_FS=y CONFIG_USB_LIBCOMPOSITE=y CONFIG_USB_ZERO=y CONFIG_CRC32=y CONFIG_CRC32_SLICEBY8=y ---8<--- Signed-off-by: Arve Hjønnevåg <arve@android.com> [yann.morin.1998@free.fr: add the resulting .config to commit log, remove unneeded USB_GADGET from the defconfig] Tested-by: "Yann E.
