[PATCH 0/2] Avoid meaningless DMA error print & use dev_err_probe
From: Alain Volmat
Date: Mon Sep 14 2020 - 06:43:20 EST
This serie replaces the patch from Holger Assmann [i2c: stm32: remove
unnecessary DMA kernel error log] (1) and the first version of [i2c: stm32:
do not display error when DMA is not requested] from myself (2).
A first patch is fixing useless error print when not being able to get
DMA channel (DMA is only optional) and also avoid printing twice an error
when a real DMA error is happening.
On top of that, dev_err_probe from Krzysztof has been rebased.
