mtd: nand: make Open Firmware device id constant

Author: Márton Németh <nm127@freemail.hu> The match_table field of the struct of_device_id is constant in so it is worth to make xps2_of_match also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { … const struct I2 *x; … }; …

netfilter: SNMP NAT: correct the size argument to kzalloc

Author: Julia Lawall <julia@diku.dk> obj has type struct snmp_object **, not struct snmp_object *. But indeed it is not even clear why kmalloc is needed. The memory is freed by the end of the function, so the local variable of pointer type should be sufficient. The semantic patch that makes this change is as follows: …
