From 7542766e78fc374d81d8c2db214c4b4308645277 Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Fri, 24 Jun 2022 21:51:12 +0200 Subject: pinctrl: qcom: spmi-gpio: make the irqchip immutable Commit 6c846d026d49 ("gpio: Don't fiddle with irqchips marked as immutable") added a warning to indicate if the gpiolib is altering the internals of irqchips. Following this change the following warning is now observed for the SPMI PMIC pinctrl driver: gpio gpiochip1: (200f000.spmi:pmic@0:gpio@c000): not an immutable chip, please consider fixing it! Fix this by making the irqchip in the SPMI PMIC pinctrl driver immutable.
