From 3fe37204c9a233d1bd852b98bca43ec61854ba78 Mon Sep 17 00:00:00 2001 From: Jia He Date: Fri, 16 Oct 2020 23:35:44 +0800 Subject: gpio: dwapb: Fix missing conversion to GPIO-lib-based IRQ-chip Commit 0ea683931adb ("gpio: dwapb: Convert driver to using the GPIO-lib-based IRQ-chip") missed the case in dwapb_irq_set_wake(). Without this fix, probing the dwapb gpio driver will hit a error: "address between user and kernel address ranges" on a Ampere armv8a server and cause a panic.
