-    solos-pci: fix double-free of TX skb in DMA mode
-    
-    We weren't clearing card->tx_skb[port] when processing the TX done interrupt.
-    If there wasn't another skb ready to transmit immediately, this led to a
-    double-free because we'd free it *again* next time we did have a packet to
-    send.

 ==
 There is a typo here so we do a double lock instead of an unlock.
