generic_defconfig explicitly disables CONFIG_INPUT_MOUSEDEV, CONFIG_INPUT_KEYBOARD & CONFIG_INPUT_MOUSE which results in warnings when merging board config fragments if any of them require these options. This is the case for the ranchu board, which means we've had the following warning when configuring for generic platform targets since commit f2d0b0d5c171 ("MIPS: ranchu: Add Ranchu as a new generic-based board"): $ make ARCH=mips 32r2el_defconfig Using ./arch/mips/configs/generic_defconfig as base Merging arch/mips/configs/generic/32r2.config Merging arch/mips/configs/generic/el.config Merging ./arch/mips/configs/generic/board-sead-3.config Merging ./arch/mips/configs/generic/board-ranchu.config Value of CONFIG_INPUT_KEYBOARD is redefined by fragment ./arch/mips/configs/generic/board-ranchu.config: Previous value: # CONFIG_INPUT_KEYBOARD is not set New value: CONFIG_INPUT_KEYBOARD=y Merging ./arch/mips/configs/generic/board-ni169445.config Merging ./arch/mips/configs/generic/board-boston.config Merging ./arch/mips/configs/generic/board-ocelot.config Merging ./arch/mips/configs/generic/board-xilfpga.config scripts/kconfig/conf --olddefconfig Kconfig # # configuration written to .config # Resolve this by removing mention of the CONFIG_INPUT_* Kconfig symbols from generic_defconfig, allowing them to take their default values & allowing board config fragments to enable them without warnings. This may be problematic if CONFIG_ARCH_MIGHT_HAVE_PC_SERIO is ever enabled for CONFIG_MIPS_GENERIC=y configurations, but for now that isn't the case so we can worry about that if & when it happens.
