Hi

I am seeing the below errors after  installing an Intel QAT card
and loading the upstreamed qat_dh895xcc and intel_qat modules.

Have others seen similar errors and know if this is a known issue
and a fix exists or know whats going on ? This is with 4.12.0-rc4+
version of the kernel.

Any help is sincerely appreciated.

thanks
--Raj
