Shaun Ruffell cb50ae1500 wctc4xxp: spin_lock() -> spin_lock_irqsave() in wctc4xxp_watchdog() 
Since commit (e10f740 "wctc4xxp: Service tx ring in interrupt handler."), it
was possible to deadlock the system if the interrupt fires while the
watchdog function is running in the context of the system timer.

This was reported by lockdep.
