->accel_id has to be large enough to hold ADF_MAX_DEVICES + 1 (which is
1025) so uint8_t is too small.
Fixes: 890c55f4dc0e ('crypto: qat - add support for c3xxx accel type')

Yes, that's correct. That was part of my next patchset, but since
you sent the patch..
We also need to change the corresponding field in the
struct adf_dev_status_info, and change the instance_id to match the
instance_id in the adf_hw_device_data struct.
I would also prefer u32 instead of unsigned int.
