From 383acb0dac033ba0fafd104a8094f0c46ff49258 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 23 Jul 2018 19:53:00 +0200 Subject: [PATCH] ARM: s5pv210: Remove legacy setting of external wakeup interrupts Since Exynos/S5Pv210 pin-controller driver is taking care about setting the external wakeup interrupts mask, the legacy code can be removed.
