Pietro Borrello 5035431c4b HID: check empty report_list in hid_validate_values()
[ Upstream commit b12fece4c64857e5fab4290bf01b2e0317a88456 ]

Add a check for empty report_list in hid_validate_values().
The missing check causes a type confusion when issuing a list_entry()
on an empty report_list.
The problem is caused by the assumption that the device must
have valid report_list. While this will be true for all normal HID
devices, a suitably malicious device can violate the assumption.

Fixes: 1b15d2e5b8 ("HID: core: fix validation of report id 0")
