Florin Malita 270c7a7215 [SERIAL] sa1100_start_tx spinlock recursion 
The serial core aquires the port spinlock before calling
port->ops->start_tx(), so sa1100_start_tx() shouldn't try to lock it
again.

BUG: spinlock recursion on CPU#0, init/1
 lock: c0205f20, .magic: dead4ead, .owner: init/1, .owner_cpu: 0
