commit 611e097d7707741a336a0677d9d69bec40f29f3d Author: Christian Borntraeger <borntraeger@de.ibm.com> hvc_console: rework setup to replace irq functions with callbacks introduced a spinlock recursion problem. request_irq tries to call the handler if the IRQ is shared. The irq handler of hvc_console calls hvc_poll and hvc_kill which might take the hvc_struct spinlock. Therefore, we have to call request_irq outside the spinlock. We can move the notifier_add safely outside the spinlock as ->data must not be changed by the backend. Otherwise, tty_hangup would fail anyway.
