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.
