Marc Zyngier a85f3e7cb7 genirq/irqdomain: Don't try to free an interrupt that has no mapping ... [ Upstream commit 4615fbc3788ddc8e7c6d697714ad35a53729aa2c ] When an interrupt allocation fails for N interrupts, it is pretty common for the error handling code to free the same number of interrupts, no matter how many interrupts have actually been allocated. This may result in the domain freeing code to be unexpectedly called for interrupts that have no mapping in that domain. Things end pretty badly. Instead, add some checks to irq_domain_free_irqs_hierarchy() to make sure that thiss does not follow the hierarchy if no mapping exists for a given interrupt.
