Arnd Bergmann 3fc202e81d HID: asus: fix build warning wiht CONFIG_ASUS_WMI disabled
asus_wmi_evaluate_method() is an empty dummy function when CONFIG_ASUS_WMI
is disabled, or not reachable from a built-in device driver. This leads to
a theoretical evaluation of an uninitialized variable that the compiler
complains about, failing to check that the hardcoded return value makes
this an unreachable code path:

In file included from include/linux/printk.h:336,
                 from include/linux/kernel.h:14,
                 from include/linux/list.h:9,
                 from include/linux/dmi.h:5,
                 from drivers/hid/hid-asus.c:29:
drivers/hid/hid-asus.c: In function 'asus_input_configured':
include/linux/dynamic_debug.h:135:3: error: 'value' may be used uninitialized in this function [-Werror=maybe-uninitialized]
   __dynamic_dev_dbg(&descriptor, dev, fmt, \
   ^~~~~~~~~~~~~~~~~
drivers/hid/hid-asus.c:359:6: note: 'value' was declared here
  u32 value;
      ^~~~~

With an extra IS_ENABLED() check, the warning goes away.
