Subject: RE: [PATCH 0/5] Remove CRYPTO_ALG_ALLOCATES_MEMORY flag

Hi Eric,

 

We are not updating the functioning of CRYPTO_ALG_ALLOCATES_MEMORY flag.
We have introduced the changes in CAAM driver and this flag is no longer
required for CAAM use-cases.

I will update the description of my patches in next version.

Thanks,
Meenakshi
