Jesper Juhl 7dd72f5189 drivers/scsi/aacraid/commctrl.c: fix mem leak in aac_send_raw_srb()
We leak in drivers/scsi/aacraid/commctrl.c::aac_send_raw_srb() :

We allocate memory:

	...
	struct user_sgmap* usg;
	usg = kmalloc(actual_fibsize - sizeof(struct aac_srb)
	  + sizeof(struct sgmap), GFP_KERNEL);

and then neglect to free it:

	...
	for (i = 0; i < usg->count; i++) {
		u64 addr;
		void* p;
		if (usg->sg[i].count >
		    ((dev->adapter_info.options &
		     AAC_OPT_NEW_COMM) ?
		      (dev->scsi_host_ptr->max_sectors << 9) :
		      65536)) {
			rcode = -EINVAL;
			goto cleanup;
	... this 'goto' makes 'usg' go out of scope and leak the memory we
	    allocated.

Other exits properly kfree(usg), it's just here it is neglected.
