From c42a01264ba1497eb3193c08ff3c2656d98250a6 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 19 Jul 2024 06:10:24 +0200 Subject: [PATCH] dma-mapping: don't return errors from dma_set_min_align_mask A NULL dev->dma_parms indicates either a bus that is not DMA capable or grave bug in the implementation of the bus code. There isn't much the driver can do in terms of error handling for either case, so just warn and continue as DMA operations will fail anyway.
