Hi David,
There is an issue with this patch. Can you please drop it.
Will send a V3, with the fixes.
The below one should be a while loop, instead of if condition.
/* If we're at the head, break out and start the mailbox
* protocol.
*/
if (list_first_entry(&adapter->mlist.list,
struct mbox_list, list) != &entry) {
int ret;
Thanks
