From b50fa1e07cf875609b9d34c5c8b32dcf11b8b603 Mon Sep 17 00:00:00 2001 From: Li RongQing Date: Mon, 15 Jun 2026 22:04:06 +0800 Subject: [PATCH] net/mlx5: Remove broken and unused mlx5_query_mtppse() mlx5_query_mtppse() reads the Event Trigger Pin (MTPPSE) register but reads the returned arm and mode values from the input buffer 'in' instead of the output buffer 'out', so it always returns the values that were written rather than the actual hardware state, making the query useless. The function has no in-tree callers. Remove it rather than fix it.
