Subject: e1000e: Remove mutex_trylock and associated WARN on failure.
X-Git-Tag: v2.6.30-rc1~662^2~736

e1000e: Remove mutex_trylock and associated WARN on failure.

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.
