[PATCH] sysfs: (rest) if show/store is missing return -EIO
sysfs: fix the rest of the kernel so if an attribute doesn't implement show or store method read/write will return -EIO instead of 0 or -EINVAL or -EPERM. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
