Hi all,

After merging the hid tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

/tmp/next/build/drivers/hid/hid-asus.c: In function 'asus_has_report_id':
/tmp/next/build/drivers/hid/hid-asus.c:732:22: error: unused variable 'err' [-Werror=unused-variable]
  732 |         int t, f, u, err = 0;
      |                      ^~~
/tmp/next/build/drivers/hid/hid-asus.c:732:19: error: unused variable 'u' [-Werror=unused-variable]
  732 |         int t, f, u, err = 0;
      |                   ^
/tmp/next/build/drivers/hid/hid-asus.c:732:16: error: unused variable 'f' [-Werror=unused-variable]
  732 |         int t, f, u, err = 0;
      |                ^
cc1: all warnings being treated as errors

Caused by commit

  Fixes: 0919db9f35832 (HID: asus: always fully initialize devices)

I have used the tree from next-20260226 instead.
