From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx> Serdev recv_buf() callback is supposed to return the amount of bytes consumed, therefore an int in between 0 and count. Do not return negative number in case of issue, just print an error and return count. This fixes a WARN in ttyport_receive_buf(). In addition to that a small cleanup patch is added on btnxpuart to remove a useless assignment.
