[PATCH 01/28] crypto: omap-aes: Fix registration of algorithms

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

 



From: Lokesh Vutla <lokeshvutla@xxxxxx>

Algorithms can be registered only once. So skip registration of
algorithms if already registered (i.e. in case we have two AES cores
in the system.)
