With the patch we will overwrite the num_sensors with a value from DT, iff specified. As probe will fail if num_sensors is 0 we can reuse ops_8996 and just not provide num_sensors for 8998, hence requiring it to be specified in DT. PS. Looking at the register spec 8996 too seems to have two tsens blocks, so in order to access sensors off the second bank this patch would be needed (and would work and be backwards compatible).
