The vgacon driver prepares a two element array of uni_pagedir_loc and uses the second item as its own reference counter for sharing the uni_pagedir. And the code assumes blindly that the second item is available if the assigned vc_uni_pagedir isn't the standard one, which might be wrong (although currently it's so). This patch fixes that wrong assumption, and gives a slight cleanup along with it: namely, instead of array, just give the uni_pagedir_loc and a separate refcount variable. It makes the code a bit more understandable at first glance. Signed-off-by: Takashi Iwai <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
