From aa36d8971fccb55ef3241cbfff9d1799e31d8628 Mon Sep 17 00:00:00 2001 From: Dillon Varone Date: Thu, 28 Dec 2023 21:36:39 -0500 Subject: [PATCH] drm/amd/display: Init link enc resources in dc_state only if res_pool presents [Why & How] res_pool is not initialized in all situations such as virtual environments, and therefore link encoder resources should not be initialized if res_pool is NULL.
