The original use of struct m_can_classdev::hrtimer was to support polling for devices without IRQ, with the timer function called hrtimer_callback(). Commit 07f25091ca02 ("can: m_can: Implement receive coalescing") uses the hrtimer for software-supported IRQ coalescence, with the timer function called m_can_coalescing_timer(). To improve the readability of the driver, rename hrtimer_callback() to m_can_polling_timer(), which better describes the functionality.
