From 37a2f8e5522abd8e206a0da1622034382aa6683d Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Wed, 21 Jun 2017 20:20:04 +0200 Subject: [PATCH] pinctrl: bcm2835: Avoid warning from __irq_do_set_handler We get a warning during boot with enabled EARLY_PRINTK that we try to set a irq_chip without data. This is caused by ignoring the return value of irq_of_parse_and_map(). So avoid calling gpiochip_set_chained_irqchip() in error case.
