Let this be consistent with writel() arguments - "val" as second arg and
"reg" as third?
You got a point there.
When considering an array of arguments in two functions and value part can be some long expression,
I think it seems more coherent.
	ufshcd_readl(hba, reg);
	ufshcd_writel(hba, reg, val);
How about keeping these?

I somehow tend to agree with what Sujit suggested. Its good to be consitent with writel() for better code readability.


Thanks,
Seungwon Jeon
