How about

	int reg = is_ab8500(di->parent) ? AB8500_USB_LINE_STAT_REG :
					  AB8500_USB_LINK1_STAT_REG;

	ret = abx500_get_register_interruptible(di->dev, AB8500_USB, reg, &val);

Shorter, clearer, and precisely fits into 80 columns -- must be good. :-)

Same here. Actually, isn't it exactly the same as above? If so, then just
factor it into its own function.
