PS1, Line 725:                  .is_sub = info_meas_ind->is_sub,
> this looks weird. You first set it and then use it to re-set it. […]
This is done on purpose because in AMR mode the caller of this function sets 
.is_sub itself. If it's set to true by the caller, then we know that it's a SUB 
frame and do nothing. If it's false, then we do some additional checks here.

Doing what you suggest would break SUB detection for AMR. The correct condition 
would be:

  if (info_meas_ind->is_sub || trx_sched_is_sacch_fn(lchan->ts, fn, true))
      ulm.is_sub = 1;

If you find this cleaner, I'll update the patch.
