sgx and kernel 4.4

[terry...@yahoo.com]

Using omap5-sgx-ddk-linux sgx driver package with Debian 4.4.80 kernel.  pvrsrvkm loads fine, but any of the sgx demo programs fails:

root@beaglebone:/usr/local/bin# ./sgx_init_test

----------------------- Start -----------------------

Try calling PVRSRVConnect with an invalid argument:

PVR:(Error): PVRSRVConnect: Invalid connection. [0, ]

PVR:(Error): PVRSRVConnect: Unable to open connection. [0, ]

 OK

Call PVRSRVConnect with a valid argument:

 OK

Try calling PVRSRVEnumerateDevices with invalid puiNumDevices:

PVR:(Error): PVRSRVEnumerateDevices: Invalid params [0, ]

 OK

Get number of devices from PVRSRVEnumerateDevices:

 OK

.... Reported 1 devices

.... Device Number  | Device Type

            0000    | PVRSRV_DEVICE_ID_SGX

Attempt to acquire device 0:

 OK

Getting SGX Client info

 OK

.... ui32ProcessID:992

Display Class API: enumerate devices

./sgx_init_test: symbol lookup error: ./sgx_init_test: undefined symbol: PVRSRVEnumerateDeviceClass

Why is this?  Is this the correct driver?

Thanks!
