Hagar Hemdan 2458f2362f irqchip/gic-v3-its: Fix potential race condition in its_vlpi_prop_update() ... commit b97e8a2f7130a4b30d1502003095833d16c028b3 upstream. its_vlpi_prop_update() calls lpi_write_config() which obtains the mapping information for a VLPI without lock held. So it could race with its_vlpi_unmap(). Since all calls from its_irq_set_vcpu_affinity() require the same lock to be held, hoist the locking there instead of sprinkling the locking all over the place. This bug was discovered using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.
