Can you please point me to other lines that need to be fixed please? It looks good
to me though it doesn't to you. I want to make sure that I'm touching the right ones.
You seem to prefer a tab following an open parenthesis in your code. Do you want me to
add a tab for every single multi-line such that it comes this for instance?


	ret = readl_poll_timeout(lldev->trca + HIDMA_TRCA_CTRLSTS_REG, val,
				 	HIDMA_CH_STATE(val) == HIDMA_CH_DISABLED, 
					1000, 10000); 

instead of

	ret = readl_poll_timeout(lldev->trca + HIDMA_TRCA_CTRLSTS_REG, val,
				 HIDMA_CH_STATE(val) == HIDMA_CH_DISABLED, 1000,
				 10000);

I'll have the pause code in OS layer call hidma_ll_enable and get rid of pause
function here.
