Subject: Initialise vga_ram_addr to 0.
X-Git-Tag: xen-3.3.0-rc1~120
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=220b939836794f4a97e5b113847884dd18e9be44;p=qemu-xen-4.3-testing.git

Initialise vga_ram_addr to 0.

This is not used in the Xen case.  In xen-unstable NULL is passed
directly in the calls to the various vga_init functions; in this
version we set vga_ram_addr to 0 as that's textually a smaller change.
