The samsung-keypad driver is implicitly selected by ARCH_EXYNOS4 (why?), but this fails if CONFIG_INPUT is a loadable module: drivers/input/built-in.o: In function `samsung_keypad_remove': drivers/input/keyboard/samsung-keypad.c:461: undefined reference to `input_unregister_device' drivers/input/built-in.o: In function `samsung_keypad_irq': drivers/input/keyboard/samsung-keypad.c:137: undefined reference to `input_event' drivers/input/built-in.o: In function `samsung_keypad_irq': include/linux/input.h:389: undefined reference to `input_event' drivers/input/built-in.o: In function `samsung_keypad_probe': drivers/input/keyboard/samsung-keypad.c:358: undefined reference to `devm_input_allocate_device' drivers/input/built-in.o:(.debug_addr+0x34): undefined reference to `input_set_capability' This changes the 'select' statement so we don't do it if CONFIG_INPUT=m. The problem does not happen on mainline kernels, as we don't normally build built-in input drivers when CONFIG_INPUT=m, but I am experimenting with a patch to change this, and the samsung keypad driver showed up as one example that was silently broken before.
