[PATCH] crypto: ecdh - remove empty exit()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Pointer members of an object with static storage duration, if not
explicitly initialized, will be initialized to a NULL pointer. The crypto
API checks if this pointer is not NULL before using it, we are safe to
remove the function.
