Subject: drivers edac: fix edac_device semaphore to mutex
From: Doug Thompson <dougthompson@xxxxxxxxxxxx>
A previous patch changed the edac_mc src file from semaphore usage to mutex
This patch changes the edac_device src file as well, from semaphore use to
mutex operation.
Use a mutex primitive for mutex operations, as it does not require a
semaphore
