Bug in keyboard driver

[Sean McNeil]

the KEY_PHONE is backwards. It returns up when pushed and down when 
released. The following change fixes it:

 static irqreturn_t neo1973kbd_aux_irq(int irq, void *dev_id)
 {
        struct neo1973kbd *neo1973kbd_data = dev_id;
 
-       int key_pressed = !gpio_get_value(irq_to_gpio(irq));
+       int key_pressed = !!gpio_get_value(irq_to_gpio(irq));
        input_report_key(neo1973kbd_data->input, KEY_PHONE, key_pressed);
        input_sync(neo1973kbd_data->input);
