| |
From: Arnd Bergmann <arnd@arndb.de>
The declaration is in an #ifdef, which causes warnings when building with 'make W=1' and without CONFIG_PM:
drivers/usb/core/devio.c:742:6: error: no previous prototype for 'usbfs_notify_suspend' drivers/usb/core/devio.c:747:6: error: no previous prototype for 'usbfs_notify_resume'
Use the same #ifdef check around the function definitions to avoid the warnings and slightly shrink the USB core.
