HID: hiddev: validate num_values for HIDIOCGUSAGES, HIDIOCSUSAGES commands
commit 93a2001bdfd5376c3dc2158653034c20392d15c5 upstream.
This patch validates the num_values parameter from userland during the
HIDIOCGUSAGES and HIDIOCSUSAGES commands. Previously, if the report id was set
to HID_REPORT_ID_UNKNOWN, we would fail to validate the num_values parameter
leading to a heap overflow.
