From: Marc Kleine-Budde Date: Thu, 7 Aug 2025 18:14:55 +0000 (+0200) Subject: can: m_can: hrtimer_callback(): rename to m_can_polling_timer() X-Git-Tag: v6.19-rc1~170^2~344^2^2~5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=60af9dbb63fb077cc71496cf5ada82261be0bb25;p=thirdparty%2Fkernel%2Flinux.git can: m_can: hrtimer_callback(): rename to m_can_polling_timer() 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.
