cf143d65c5 HID: i2c-hid: add Trekstor Primebook C11B to descriptor override
commit 09f3dbe474735df13dd8a66d3d1231048d9b373f upstream.

The Primebook C11B uses the SIPODEV SP1064 touchpad. There are 2 versions
of this 2-in-1 and the touchpad in the older version does not supply
descriptors, so it has to be added to the override list.

9c18625661 i2c-hid: properly terminate i2c_hid_dmi_desc_override_table[] array
commit b59dfdaef173677b0b7e10f375226c0a1114fd20 upstream.

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.

8e271100ef HID: i2c-hid: override HID descriptors for certain devices
[ Upstream commit 9ee3e06610fdb8a601cde59c92089fb6c1deb4aa ]

A particular touchpad (SIPODEV SP1064) refuses to supply the HID
descriptors. This patch provides the framework for overriding these
descriptors based on DMI data. It also includes the descriptors for
said touchpad, which were extracted by listening to the traffic of the
windows filter driver, as well as the DMI data for the laptops known
to use this device.
