From 2de9fd17c0359fea0c2ab5ae393c40d6d299bcaf Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Wed, 12 Feb 2014 20:19:07 -0700 Subject: [PATCH] ACPI / button: fix button driver compile error when CONFIG_PM_SLEEP is undefined MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ACPI button driver defines acpi_button_resume() when CONFIG_PM_SLEEP is defined.
