From 71b96c3a8a2d35f74ca7559f9d1b123d97da6f4f Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 23 May 2017 20:41:39 +0200 Subject: pinctrl: samsung: Constify wakeup driver specific data Static exynos_irq_chip structures, containing driver specific data, are referenced only through opaque data pointer in const of_device_id table. The contents of pointed memory (exynos_irq_chip structure itself) is then copied with kmemdup() during wakeup initialization so exynos_irq_chip can be made const for code safenes.
