From 23845fa10bc135bfc7fd4380948b5965b9d20cb5 Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Mon, 27 Feb 2023 16:56:25 -0800 Subject: [PATCH] gpio-button-hotplug: do not error on interrupt attached keys The Linux gpio-keys driver bindings allow for GPIO attached or interrupt attached keys. Currently if an interrupt attached key is encountered gpio_keys_button_probe() will fail due to not being able to get a gpio descriptor: gpio-keys: probe of gpio-keys failed with error -2 Skip the failure in the case of interrupt attached keys to resolve this.
