sparc: use scnprintf() in show_pciobppath_attr() in vio.c
snprintf() returns the number of bytes that would be written, which may be greater than the the actual length to be written. show_pciobppath_attr() should return the number of bytes printed into the buffer. This is the return value of scnprintf(). Signed-off-by: Chen Zhou <chenzhou10@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
