If anyone has any objections, please let me know. ------------------ From: Larry Finger commit 9452bf560273e4de2395ffdd79024debfb0c1290 upstream. This makes the follow-on check for psta != NULL pointless and makes the whole exercise rather pointless. This is another case of why blindly zero-initializing variables when they are declared is bad.
