[PATCH] sony-laptop/thinkpad-acpi: fix build error

[Andreas Herrmann <aherrman@arcor.de>]

sony-laptop and thinkpad-acpi make use of input-core functions.
Hence you get link errors if those drivers are built but CONFIG_INPUT
is not set. Attached patch fixes this minor issue.


Regards,

Andreas

Build errors if CONFIG_SONY_LAPTOP && !INPUT or
if CONFIG_THINKPAD_ACPI && !INPUT:

 LD      vmlinux
    ...
drivers/built-in.o: In function `sony_laptop_remove_input':
sony-laptop.c:(.text+0x768fb): undefined reference to `input_unregister_device'
    ...
drivers/built-in.o: In function `thinkpad_acpi_module_exit':
thinkpad_acpi.c:(.text+0x78c1b): undefined reference to `input_free_device'
    ...

I suggest to auto-select CONFIG_INPUT for both drivers.
