    Date
    Use kzalloc instead of kmalloc + memset.

    The semantic patch that makes this change is:
    (https://coccinelle.gitlabpages.inria.fr/website/)

    expression res, size, flag;

    - res = kmalloc(size, flag);
    + res = kzalloc(size, flag);
    ...
    - memset(res, 0, size);
    //</smpl>
