For Panel Replay with AUX-less ALPM (link-off PR), the source must send Adaptive-Sync SDP v2. Program DB[1:0] per DP spec v2.1: - VRR AVT: 00b (variable VTotal) - VRR FAVT: 10b/11b (TRR not reached/reached) - Fixed timing with PR link-off (VRR off): 01b (AS disabled; VTotal fixed)
Also, drop the redundant target_rr assignment. v2: Fix the else case.
