If the dma channel request error code is EPROBE_DEFER there is no need to
print error message.

Hi Hans,
the patch updates the v1 "media: rcar_drif: Use dma_request_chan() instead
dma_request_slave_channel()" which got applied to the v3 state.
I have not added the fixes line, but if you think the hash is not going to
change, you can copy this line:
Fixes: 1b5482e0d268 ("media: rcar_drif: Use dma_request_chan() instead dma_request_slave_channel()")
Regards,
Peter
