Subject: ui: rename cursor_{get->ref}, return it
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2512a026fab8d526e623426a3002599a2de09d16;p=qemu.git

ui: rename cursor_{get->ref}, return it

The naming is more conventional in QEMU code, and allows to simplify
some code by changing the API design, so it returns the input parameter,
instead of void.
