sysfs: create __ATTR_WO()
This creates the macro __ATTR_WO() for write-only attributes, instead of having to "open define" them. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> (cherry picked from commit a65fcce75a75c0d41b938f86d09d42b6f1733309) Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org>
