Single-thread access must be ensured for ICH8 NVM and PHY operations. This synchronization is provided by the nvm_mutex. To assist in understanding the contexts from which this code could be reached, a WARN was output if the mutex was not going to be immediately acquirable (if !mutex_trylock()). The code has now been optimized, and we have verified that the few remaining mutex contentions are reasonable and non-blocking, and it is time to remove the mutex_trylock() and WARN messages.
