From 0a25cb5544f4f01d2e7c06164555fd9cd6eb64fd Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 10 Feb 2022 09:27:21 +0000 Subject: genirq/debugfs: Use irq_print_chip() when provided by irqchip Since irqchips have the option to implement irq_print_chip, use this when available to output the irqchip name in debugfs.
