Subject: [PATCH -next] usb: renesas_usbhs: Fix unused function warning when CONFIG_PM not set
Date:   Thu, 13 Dec 2018 11:19:24 +0800
Message-ID: <20181213031924.12216-1-yuehaibing@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

with CONFIG_PM not set, gcc warning this:
drivers/usb/renesas_usbhs/common.c:844:12:
 warning: 'usbhsc_suspend' defined but not used [-Wunused-function]
drivers/usb/renesas_usbhs/common.c:860:12:
 warning: 'usbhsc_resume' defined but not used [-Wunused-function]

fix this by adding #ifdef around it.
