It seems nobody tested the debug() option in spin_lock_irqsave(). Currently, when #define DEBUG, it spoils the compiler with
In file included from drivers/usb/dwc3/gadget.c:18: drivers/usb/dwc3/gadget.c: In function ‘dwc3_gadget_set_selfpowered’: include/log.h:235:4: warning: ‘flags’ is used uninitialized in this function [-Wuninitialized] 235 | printf(pr_fmt(fmt), ##args); \ | ^~~~~~ drivers/usb/dwc3/gadget.c:1347:17: note: ‘flags’ was declared here 1347 | unsigned long flags; | ^~~~~
and so on... Drop useless debug() call to make compiler happy.
