Ugh ... I missed this obvious CodingStyle error.

What Dave is trying to say is that he (and I'm pretty sure everyone else
for that matter) disagree with you style change because you have not broken
the columns into "sensible chunks".

IOW ... this,

	if (tmo == 0 ||
	    dma->device_tx_status(dma_chan, cookie, NULL) != DMA_COMPLETE) {

is much easier to comprehend than this,

	if (tmo == 0 || dma->device_tx_status(dma_chan, cookie, NULL)
			!= DMA_COMPLETE) {
