Fbcon issue

Hi
while doing some bug hunting for another project I discovered an issue which is imho a bug in fbcon.
The problem is that each virtual console has its own color palette but the framebuffer only has one color map.
So, for example, if im running fbcon on vt1 and set there a non-default colormap and then allocate a new vt, for which the standard color palette is set, also the framebuffer colormap is set back to the default.Which will lead to color corruption on the actual vt. A fix could be to allow setting of color palette only for the foreground console,
ie change following in fbcon.c: fbcon_set_palette() at line 2400:

if (fbcon_is_inactive(vc, info))

               return -EINVAL;

to

if ( fbcon_is_inactive(vc, info) || (vc->vc_num != fg_console) )

               return -EINVAL;
