Subject: [PATCH] fix(vdisplay/windows): DISPLAYCONFIG_PATH_SOURCE_INFO union
 field access
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

modeInfoIdx lives in the Anonymous union (windows-rs), not directly on
sourceInfo — set_virtual_primary_ccd now reads .Anonymous.modeInfoIdx.
