From 72780ce5f1a4189f3c8dcfb1c596c65146452668 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 13 Jan 2020 23:08:00 +0100 Subject: gpio: Drop the chained IRQ handler assign function gpiochip_set_chained_irqchip() would assign a chained handler to a GPIO chip. We now populate struct gpio_irq_chip for all chained GPIO irqchips so drop this function.
