floppy: use del_timer_sync() in init cleanup
When no floppy is found the module code can be released while a timer function is pending or about to be executed. CPU0 CPU1 floppy_init() timer_softirq() spin_lock_irq(&base->lock); detach_timer(); spin_unlock_irq(&base->lock); -> Interrupt del_timer(); return -ENODEV; module_cleanup(); <- EOI call_timer_fn(); OOPS Use del_timer_sync() to prevent this.
