vt8623fb: fix kernel oops
commit 20e061fb750d36ec0ffcb2e44ed7dafa9018223b Author: Ondrej Zajicek <santiago@crfreenet.org> Date: Mon Apr 28 02:15:18 2008 -0700 fbdev: framebuffer_alloc() fixes Correct the dev arg of framebuffer_alloc() in arkfb, s3fb and vt8623fb. causes a null-pointer deref because "info->dev is NULL, info was just kzallocated".
