Lina Iyer 5998cfe1a3 ANDROID: GKI: drivers: mailbox: fix race resulting in multiple message submission ... The mailbox sends a request to the controller and the tx_done callback received for that request clears the active_req pointer. The callback sends the next request in the queue, if there is one. When a controller is busy and cannot accept any more requests until the interrupt is cleared, it would return -EAGAIN. The mailbox controller must unlock its spinlock and retry again.
