From a724a63b256e402422dfc90c7938fd26cd6260bf Mon Sep 17 00:00:00 2001 From: Cristian Ciocaltea Date: Fri, 10 Feb 2023 22:21:26 +0200 Subject: [PATCH] net: stmmac: Restrict warning on disabling DMA store and fwd mode commit 05d7623a892a9da62da0e714428e38f09e4a64d8 upstream. When setting 'snps,force_thresh_dma_mode' DT property, the following warning is always emitted, regardless the status of force_sf_dma_mode: dwmac-starfive 10020000.ethernet: force_sf_dma_mode is ignored if force_thresh_dma_mode is set. Do not print the rather misleading message when DMA store and forward mode is already disabled. Fixes: e2a240c7d3bc ("driver:net:stmmac: Disable DMA store and forward mode if platform data force_thresh_dma_mode is set.")
