[PATCH 0/7] HID: roccat: validate raw report lengths

[Jiale Yao <yaojiale02@163.com>]

Roccat raw event callbacks receive the report before HID core validates
and pads its length.  Seven callbacks inspect fixed-format reports without
first ensuring that the complete report was received.

Add per-driver length checks before parsing or forwarding these reports.
The first five patches protect helpers which read fixed fields, while the
konepure and ryos patches additionally prevent a fixed-size copy of a
truncated report into the Roccat character-device event stream.

Each patch is independent and fixes the driver named in its subject.
