commit f7471b63091dbad30db257ec49eed0e559033c7a
Author: Nico Huber

Fix random warnings in char_io.c

Fix two warnings:

char_io.c: In function 'grub_printf':
    char_io.c:86:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable]

char_io.c: In function 'init_page':
    char_io.c:104:4: warning: implicit declaration of function 'get_cb_version' [-Wimplicit-function-declaration]

by removing the variable 'ret' and including sys_info.h for the
    'get_cb_version' prototype.
