Merge branch 'for-5.12/core' into for-linus

- improved handling of generic HID keyboard (no more splitting system
  and consumer controls away), in order to make it easier for userspace
  to figure out the details of the device easier. From Dmitry Torokhov.

- report data sanitization fixes from Will McVicker and Randy Dunlap
