On SDMA initialization return exactly the same error, which is
reported by dma_request_slave_channel_reason(), it is a preceding
change to defer SPI DMA initialization, if SDMA module is not yet
available.

Maybe something like: "fix probe deferral when dmaengine is not yet
available" in the subject line will better express that this is a patch
that should be applied ASAP. Also you can move this up to the front of
the series when resending.

This patch itself does not implement deferral for spi-imx if dmaengine 
not ready. The patch targets 2 things: give a bit more detailed error 
information of SPI dma slave channel initialization error and provide a 
basis for the next patch ([PATCH v3 7/7] spi: imx: defer spi 
initialization, if DMA engine is pending).
