Subject: [PATCH 02/27] drm/amd/display: Fix p-state type when p-state is unsupported
Date: Tue, 25 Feb 2025 14:35:45 +0800 [thread overview]
Message-ID: <20250225063610.631461-3-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20250225063610.631461-1-Wayne.Lin@amd.com>
From: Dillon Varone <Dillon.Varone@amd.com>
[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.
