Note: this is a different debugging session, different traceback, but
same kernel.
$ gdb ./vmlinux

(gdb) l *(dwc3_gadget_ep_dequeue + 0x14c)
0xf81b50ac is in dwc3_gadget_ep_dequeue (./include/linux/spinlock.h:342).
337 raw_spin_lock_nest_lock(spinlock_check(lock), nest_lock);
\
338 } while (0)
339
340 static __always_inline void spin_lock_irq(spinlock_t *lock)
341 {
342 raw_spin_lock_irq(&lock->rlock);
343 }
344
345 #define spin_lock_irqsave(lock, flags) \
346 do { \
Which is likely the spin_lock_irqsave call early in the function.
