HID: hidraw: add HIDIOCREVOKE ioctl
There is a need for userspace applications to open HID devices directly.
Use-cases include configuration of gaming mice or direct access to
joystick devices. The latter is currently handled by the uaccess tag in
systemd, other devices include more custom/local configurations or just
sudo.
A better approach is what we already have for evdev devices: give the
application a file descriptor and revoke it when it may no longer access
that device.
This patch is the hidraw equivalent to the EVIOCREVOKE ioctl, see
commit c7dc65737c9a ("Input: evdev - add EVIOCREVOKE ioctl") for full
details.
