This patch removes the null test on lun_cg. lun_cg is initialized at the beginning of the function to &lun->lun_group. Since lun_cg is dereferenced prior to the null test, it must be a valid pointer. The following Coccinelle script is used for detecting the change: @r@ expression e,f; identifier g,y; statement S1,S2; @@ *e = &f->g <+... f->y ...+> *if (e != NULL || ...)
