usb: musb: fix compilation warning on unused function
commit c8bd2ac3b4c6c84c4a7cdceaed626247db698ab2 upstream.
The function musb_run_resume_work is called only when CONFIG_PM is
enabled. So this function should not be defined when CONFIG_PM is
disabled. Otherwise the compiler issues a warning:
drivers/usb/musb/musb_core.c:2057:12: error: ‘musb_run_resume_work’ defined but
not used [-Werror=unused-function]
static int musb_run_resume_work(struct musb *musb)
