Subject: [PATCH] drm/amd/display: Avoid flooding unnecessary info messages
Date: Tue, 13 May 2025 11:20:24 +0800	[thread overview]
Message-ID: <20250513032026.838036-1-Wayne.Lin@amd.com> (raw)

It's expected that we'll encounter temporary exceptions
during aux transactions. Adjust logging from drm_info to
drm_dbg_dp to prevent flooding with unnecessary log messages.

Fixes: 6285f12bc54c ("drm/amd/display: Fix wrong handling for AUX_DEFER case")
