From 4ba50df685e85b9d912a290d9614ffbeb4d9f060 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 1 Apr 2009 14:39:20 +0000 Subject: [PATCH] input: sh_keysc: use enable/disable_irq_wake() Modify the sh_keysc driver to use enable/disable_irq_wake() during suspend and resume. These functions are used to enable the sh_keysc interrupt in the interrupt controller so the keypad can be used to wakeup the system from suspend.
