Re: [PATCH v2] xen/arm: irq: add missing spin_unlock() in init_local_irq_data() error path



Hi Mykola,

If init_one_irq_desc() fails, init_local_irq_data() returns without
releasing local_irqs_type_lock, leading to a possible deadlock.

Release the lock before returning to ensure proper cleanup.

Fixes: 2bb32b809250 ("xen/irq: Propagate the error from init_one_desc_irq() in 
init_*_irq_data()")

I will commit the patch soon.
