From db651ace499c5c81408ce333cf065d1b4dd734d9 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Thu, 28 Oct 2021 10:52:43 +0200 Subject: [PATCH] gpio: realtek-otto: fix GPIO line IRQ offset [ Upstream commit 585a07079909ba9061ddd88214c36653e1aef71a ] The irqchip uses one domain for all GPIO lines, so the line offset should be determined w.r.t. the first line of the first port, not the first line of the triggered port.
