From a538d6137dffc5dc8082b9ebe9819c4106fa3f83 Mon Sep 17 00:00:00 2001 From: "Pandiyan, Dhinakaran" Date: Thu, 16 Mar 2017 00:10:24 -0700 Subject: drm/dp: Kill total_pbn and total_slots in struct drm_dp_mst_topology_mgr The total vcpi time slots is always 63 and does not depend on the link BW, remove total_slots from MST topology manager struct. The next change is to remove total_pbn which is hardcoded to 2560. The total PBN that the topology manager allocates from depends on the link rate and is not a constant. So, fix this by removing the total_pbn member itself.
