From 44da03628b841635b157ea8d3fd46626783fe70d Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Thu, 16 Apr 2020 12:34:53 -0300 Subject: [PATCH] serial: fsl_lpuart: Change DMA failure messages to debug level Currently the following messages are seen when booting i.MX8QXP: fsl-lpuart 5a060000.serial: DMA tx channel request failed, operating without tx DMA (-19) fsl-lpuart 5a060000.serial: DMA rx channel request failed, operating without rx DMA (-19) It is not really useful to have such messages on every boot, so change them to debug level instead.
