Pull HID updates from Benjamin Tissoires:
- rewrite of the HID-BPF internal implementation to use bpf struct_ops
instead of a tracing endpoint (Benjamin Tissoires)
- add two new HID-BPF hooks to be able to intercept userspace calls
targeting a HID device and filtering them (Benjamin Tissoires)
- add support for various new devices through HID-BPF filters (Benjamin
Tissoires)
- add support for the magic keyboard backlight (Orlando Chamberlain)
- add the missing MODULE_DESCRIPTION() macros in HID drivers (Jeff
Johnson)
- use of kvzalloc in case memory gets too fragmented (Hailong Liu)
- retrieve the device firmware node in the child HID device (Danny
Kaehn)
- some hid-uclogic improvements (José Expósito)
- some more typos, trivial fixes, kernel doctext and unused functions
cleanups
