Subject: [PATCH 091/482] * grub-core/io/bufio.c (grub_bufio_open): Use
grub_zalloc instead of explicitly zeroing elements. * grub-core/io/gzio.c
(grub_gzio_open): Likewise. * grub-core/io/lzopio.c (grub_lzopio_open):
Remove explicit zeroing of elements in a structure already allocated using
grub_zalloc. * grub-core/io/xzio.c (grub_xzio_open): Likewise.
