From c7a0aa59524c5bb20bebaca360f7c5faaec6b806 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Tue, 7 Nov 2017 19:15:48 +0100 Subject: [PATCH] gpio: Move irq_handler to struct gpio_irq_chip In order to consolidate the multiple ways to associate an IRQ chip with a GPIO chip, move more fields into the new struct gpio_irq_chip.
