Subject: [PATCH v3 1/3] vnc: move check into vnc_cursor_define
Date: Tue, 12 Jan 2021 14:41:18 +0100	[thread overview]
Message-ID: <20210112134120.2031837-2-kraxel@redhat.com> (raw)
In-Reply-To: <20210112134120.2031837-1-kraxel@redhat.com>

Move the check whenever a cursor exists into the vnc_cursor_define()
function so callers don't have to do it.
