ARM: exynos: don't select keyboard driver
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 removes the 'select' as suggested by Krzysztof Kozlowski and instead enables the driver from the defconfig files. 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.
