From ec7282bd2688c6c741c79f8696a68c6c0403cf2d Mon Sep 17 00:00:00 2001 From: Artem Grishin Date: Thu, 1 Jun 2023 12:52:16 -0400 Subject: drm/amd/display: Bug fix in dcn315_populate_dml_pipes_from_context [Why] When iterating over all pipes in the loop, the CRB allocation algorithm may potentially skip some of the pipes. Previously, the current pipe index didn't get updated in this case, causing incorrect outcome. [How] Increment the pipe index when skipping over a pipe in the loop.
