The variables A,HBS and VBS are never read in XGIfb_mode_rate_to_ddata and the assignment has no side effects -> so we can simply remove them. Removing them causes VT, HT and cr_data3 to be unused -> remove them as well and remove the assignmens to cr_data which are shadowed by a different assignment a few lines later.
