[PATCH 06/19] drm/amd/display: Adjust secure_display_context data structure
Aurabindo Pillai
aurabindo.pillai at amd.com
Tue Dec 3 21:39:44 UTC 2024
From: Wayne Lin <Wayne.Lin at amd.com>
[Why]
Variables relates to secure display are spreading out within struct
amdgpu_display_manager.
[How]
Encapsulate relevant variables into struct secure_display_context and
adjust relevant affected codes.
