Subject: [PATCH] chardev/baum: fix baum that releases brlapi twice
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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)"
