From 9a9c3e1fe5256da14a0a307dff0478f90c55fc8c Mon Sep 17 00:00:00 2001 From: Wayne Lin Wayne.Lin@amd.com Date: Tue, 13 May 2025 11:20:24 +0800 Subject: [PATCH] drm/amd/display: Avoid flooding unnecessary info messages
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.
