Subject: x86: qemu: Remove call to vgabios execution
X-Git-Tag: v2016.01-rc1~4^2~7
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=20cbafa6fab07303d525a3473a27c90c67e85ed6;p=oweals%2Fu-boot.git

x86: qemu: Remove call to vgabios execution

The call to pci_run_vga_bios() is not needed as this is handled
in the vesa_fb driver.
