[Qemu-devel] [PATCH] milkymist: softmmu: fix event handling

[Michael Walle]

Keys which send more than one scancode (esp. windows key) weren't handled
correctly since commit 1ff5eedd. Two events were put into the input event
queue but only one was processed. Fixes this by fetching all pending
events in the callback handler.
