------------------------------------------------------
Subject: fbdev: save the activate field before calling fb_check_var()
From: "Antonino A. Daplas" <adaplas@xxxxxxxxx>
Some drivers may reset the var->activate field on fb_check_var(). This can
lead to undefined behavior. For example, doing fbset -a <option> with vga16fb
will only modify the active console instead of modifying all.
