Separate interrupt descriptors lookup from allocation. It was possible to perform config on non-existing interrupt simply by allocating spurious descriptor. Must lock the interrupt descriptors table lookup to avoid mismatches. This ought to prevent trouble while setting up new interrupt and dispatching existing one. Use spin mutex rather than sleep mutex. This is mainly due to lock in arm_dispatch_intr. This should be eventually changed to a lock-less solution without walking through a linked list on each interrupt.
