[PATCH v3 0/3] HID: hidraw: rework ioctls

[Benjamin Tissoires <bentiss@kernel.org>]

Arnd sent the v1 of the series in July, and it was bogus. So with a
little help from claude-sonnet I built up the missing ioctls tests and
tried to figure out a way to apply Arnd's logic without breaking the
existing ioctls.

The end result is in patch 3/3, which makes use of subfunctions to keep
the main ioctl code path clean.
