commit c9d655dccea0cb6df20ba5b39294a24be045ea4f
Author: Fabio Estevam <fabio.estevam@...escale.com>
Date:   Wed Nov 19 12:37:53 2014 -0200

    usb: dwc2: Fix build warning when CONFIG_PM_SLEEP=n
    
    Building with bcm2835_defconfig, which has CONFIG_PM_SLEEP=n causes the
    following build warning:
    
    drivers/usb/dwc2/platform.c:227:12: warning: 'dwc2_suspend' defined but not used [-Wunused-function]
    drivers/usb/dwc2/platform.c:237:12: warning: 'dwc2_resume' defined but not used [-Wunused-function]
    
    Annotate these functions with '__maybe_unused' to prevent the warnings.

that's the head of my branch, which is testing/next. And I don't have
