-Subject: [PATCH] net: mvneta: Fix spinlock usage
-
-In the previous patch, the spinlock was not initialized. While it didn't
-cause any trouble yet it could be a problem to use it uninitialized.
-
-The most annoying part was the critical section protected by the spinlock
-in mvneta_stop(). Some of the functions could sleep as pointed when
-activated CONFIG_DEBUG_ATOMIC_SLEEP. Actually, in mvneta_stop() we only
-need to protect the is_stopped flagged, indeed the code of the notifier
-for CPU online is protected by the same spinlock, so when we get the
-lock, the notifer work is done.
