From 3964576307edf408435949633b1f600262d70bb6 Mon Sep 17 00:00:00 2001 From: Alexander Shiyan Date: Thu, 31 Jan 2019 11:46:11 +0300 Subject: [PATCH] can: mcp251x: Use dev_name() during request_threaded_irq() Passing driver name as name during request_threaded_irq() results in all CAN IRQs have same name. This does not help much to easily identify which IRQ belongs to which CAN instance. Therefore pass dev_name() during request_threaded_irq() so that better identifiable name is listed for CAN devices in cat /proc/interrupts output.
