From 8e6bd945e6dde64fbc60ec3fe252164493a8d3a2 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 16 May 2023 22:17:42 +0200 Subject: [PATCH] usb: hide unused usbfs_notify_suspend/resume functions 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.
