[Qemu-devel] [PATCH target-arm v2 02/11] char/cadence_uart: Add missing uart_update_state

[Peter Crosthwaite]

This should be rechecked on bus write accesses as such accesses may
change the underlying state that generates the interrupt. Particular
relevant for when the guest touches the interrupt status or mask.
