1ef7c96ee2 baum: Truncate braille device size to 84x1 
Baum device bigger than 84 do not actually exist, but the user's own
Braille device might be wider than 84 columns.  Some guest drivers
would be upset by such sizes, so clamp the device size.

98e8790326 chardev/baum: fix baum that releases brlapi twice 
Error process of baum_chr_open needs to set brlapi null, so it won't
get released twice in char_braille_finalize, which will cause
"/usr/bin/qemu-system-x86_64: double free or corruption (!prev)"
