Maybe add ep_<level> helper macros and remove xprint

#define ep_err(ep, fmt, ...)					\
	dev_err(&(ep)->dev->pdev->dev, fmt, ##__VA_ARGS__)
#define ep_warn(ep, fmt, ...)					\
	dev_warn(&(ep)->dev->pdev->dev, fmt, ##__VA_ARGS__)
#define ep_info(ep, fmt, ...)					\
	dev_info(&(ep)->dev->pdev->dev, fmt, ##__VA_ARGS__)
#define ep_dbg(ep, fmt, ...)					\
	dev_dbg(&(ep)->dev->pdev->dev, fmt, ##__VA_ARGS__)
#define ep_vdbg(ep, fmt, ...)					\
	dev_vdbg(&(ep)->dev->pdev->dev, fmt, ##__VA_ARGS__)

but even that conversion isn't straightforward.
