From a895014853ea6df2778533e2a0bb7a0d53f02ec2 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 19 Sep 2022 12:36:29 -0400 Subject: [PATCH] drm/amd/display: fix transfer function passed to build_coefficients() The default argument should be enum TRANSFER_FUNCTION_SRGB rather than the current boolean value which improperly maps to TRANSFER_FUNCTION_BT709. Commit 9b3d76527f6e ("drm/amd/display: Revert adding degamma coefficients") looks to have improperly reverted commit d02097095916 ("drm/amd/display: Add regamma/degamma coefficients and set sRGB when TF is BT709") replacing the enum value with a boolean value.
