[PATCH] hyperv: Add missing field to hv_output_map_device_interrupt

From: Nuno Das Neves
Date: Wed Aug 13 2025 - 14:21:14 EST


This field is unused, but the correct structure size is needed
when computing the amount of space for the output argument to
reside, so that it does not cross a page boundary.
