From 38702cce547a74493687fd8bb925fbb5c3898ce3 Mon Sep 17 00:00:00 2001 From: Maxim Mikityanskiy Date: Fri, 29 Mar 2019 15:37:51 -0700 Subject: [PATCH] net/mlx5: Remove unused MLX5_*_DOORBELL_LOCK macros MLX5_*_DOORBELL_LOCK macros provided a way to avoid locking for mlx5_write64 on 64-bit platforms where it's not necessary. Currently all calls to mlx5_write64 don't use a spinlock, so the macros became unused.
