Stephen notes:
After merging the usb tree, today's linux-next build (sparc64 defconfig)
failed like this:
drivers/usb/core/hub.c: In function 'port_event':
drivers/usb/core/hub.c:4853:2: error: implicit declaration of function
'hub_handle_remote_wakeup' [-Werror=implicit-function-declaration]
Caused by commits af376a461cf0 ("usb: refactor port handling in
hub_events()") and 7e73be227b15 ("usb: hub_handle_remote_wakeup()
depends on CONFIG_PM_RUNTIME=y") This build has CONFIG_PM not set ...
The kbuild robot also reported this.
