    Input: sirfsoc-onkey - allow modular build · af6e9463

    CONFIG_INPUT may itself be a loadable module, but the sirf power key
    driver is listed as 'bool', which makes it possible to select
    a broken configuration with the driver built-in but the subsystem
    not loaded. In this configuration, we get a link error:
    
    drivers/input/built-in.o: In function `sirfsoc_pwrc_isr':
    drivers/input/misc/sirfsoc-onkey.c:63: undefined reference to `input_event'

    This marks the driver as 'tristate' so it becomes possible to have
    it in a loadable module, mainly to help with randconfig builds.
    
    We also have to add a missing semicolon here, which ended up not
    being needed in built-in mode because the following MODULE_DEVICE_TABLE
    is an empty macro followed by another semicolon then.
