[PATCH 06/16] crypto: authenc - Only access common skcipher fields on spawn

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

 



As skcipher spawns may be of the type lskcipher, only the common
fields may be accessed.  This was already the case but use the
correct helpers to make this more obvious.
