From 49f0054e18102774db7f5bd0cf847b5219f6c3fd Mon Sep 17 00:00:00 2001 From: Dillon Varone Date: Wed, 12 Feb 2025 17:06:42 -0500 Subject: [PATCH] drm/amd/display: Fix p-state type when p-state is unsupported [ Upstream commit a025f424af0407b7561bd5e6217295dde3abbc2e ] [WHY&HOW] P-state type would remain on previously used when unsupported which causes confusion in logging and visual confirm, so set back to zero when unsupported.
