Release 4.14 drivers/hid/hidraw.c
/*
* HID raw devices, giving access to raw HID events.
*
* In comparison to hiddev, this device does not process the
* hid events at all (no parsing, no lookups). This lets applications
* to work on raw hid events as they want to, and avoids a need to
* use a transport-specific userspace libhid/libusb libraries.
