From f9f403218e1ca947a1a017be01da6ae7fb637eba Mon Sep 17 00:00:00 2001 From: Melissa Wen Date: Tue, 13 May 2025 18:38:17 -0300 Subject: [PATCH] drm/amd/display: only collect data if debug gamut_remap is available Color gamut_remap state log may be not available for some hw versions, so prevent null pointer dereference by checking if there is a function to collect data for this hw version.
