#     i2c-hid: properly terminate i2c_hid_dmi_desc_override_table[] array
#     
#     Commit 9ee3e06610fd ("HID: i2c-hid: override HID descriptors for certain
#     devices") added a new dmi_system_id quirk table to override certain HID
#     report descriptors for some systems that lack them.
#     
#     But the table wasn't properly terminated, causing the dmi matching to
#     walk off into la-la-land, and starting to treat random data as dmi
#     descriptor pointers, causing boot-time oopses if you were at all
#     unlucky.
#     
#     Terminate the array.
#     
#     We really should have some way to just statically check that arrays that
#     should be terminated by an empty entry actually are so.  But the HID
#     people really should have caught this themselves, rather than have me
#     deal with an oops during the merge window.  Tssk, tssk.
