Subject: vnc: Fix fatal crash with vnc reverse mode
X-Git-Tag: v0.14.1~19
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=74b121a007c52b435870def4b1f1e6c42042bf51;p=thirdparty%2Fqemu.git

vnc: Fix fatal crash with vnc reverse mode

Reverse mode is unusable:

	qemu -vnc localhost:5500,reverse

crashes in vnc_refresh_server_surface because some pointers are NULL.

Fix this by calling vnc_dpy_resize (which initializes these pointers)
before calling vnc_refresh.
