driver inclusion category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/9262 ---------------------------------------------------------------------- Width of instant number is default to 32, shift left with theoretically max order (bigger than 32) may make the number overflow. Change the declaration of the number to unsigned long, aligning with the parameter type declaration of the funcion.
