Subject: [PATCH -next v2 0/2] jffs2: fix two memory leak when mount jffs2

V1->V2:
	In jffs2_scan_medium,
	if s = kzalloc(sizeof(struct jffs2_summary), GFP_KERNEL);
	returns error, go to "out" to do clear. Null pointer dereference
	occurs when if (s->sum_list_head) is executed in "out".

  jffs2: fix memory leak in jffs2_scan_medium
