There are unused variables without CONFIG_OF:
drivers/input/misc/twl4030-pwrbutton.c:41:44: error: unused variable 'twl4030_chipdata' [-Werror,-Wunused-const-variable]
   41 | static const struct twl_pwrbutton_chipdata twl4030_chipdata = {
      |                                            ^~~~~~~~~~~~~~~~
drivers/input/misc/twl4030-pwrbutton.c:46:44: error: unused variable 'twl6030_chipdata' [-Werror,-Wunused-const-variable]
   46 | static const struct twl_pwrbutton_chipdata twl6030_chipdata = {

Fix that by avoiding some #ifdef CONFIG_OF
