Oliver Upton 57c80836ce KVM: arm64: vgic-its: Test for valid IRQ in its_sync_lpi_pending_table()
commit 8d3a7dfb801d157ac423261d7cd62c33e95375f8 upstream.

vgic_get_irq() may not return a valid descriptor if there is no ITS that
holds a valid translation for the specified INTID. If that is the case,
it is safe to silently ignore it and continue processing the LPI pending
table.
