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.

accel_id has to be large enough to hold ADF_MAX_DEVICES + 1
(which is > 1025) so uint8_t is too small.
