[PATCH] crypto: caam: Clear some memory in instantiate_rng()

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

 



According to the comment at the end of the 'for' loop just a few lines
below, it looks needed to clear 'desc'.

So it should also be cleared for the first iteration.

This patch is speculative, but can't hurt.

Maybe the memset() at the end of the 'for' loop could be removed instead.
