[PATCH] drm, ast_fb: Fix a small leak in astfb_create()

[Jesper Juhl]

We have this code:

...
	sysram = vmalloc(size);
	if (!sysram)
		return -ENOMEM;

	info = framebuffer_alloc(0, device);
	if (!info) {
		ret = -ENOMEM;
		goto out;
	}
...

We'll leak the memory allocated to 'sysram' if the framebuffer_alloc()
call fails and the variable goes out of scope.
