From c607e5e2e4f4dc6e91da6fd81280f0474fdb6cd4 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Thu, 9 Jul 2020 20:12:01 +0300 Subject: [PATCH] gpio: max77620: Don't shadow error code of platform_get_irq() The platform_get_irq() returns a positive interrupt number on success and negative error code on failure (zero shouldn't ever happen in practice, it would produce a noisy warning). Hence let's return the error code directly instead of overriding it with -ENODEV.
