> Subject: [PATCH] crypto/qat: fix docsis segmentation fault
> 
> Currently if AES or DES algorithms fail for Docsis test suite,
> a segmentation fault occurs when cryptodev_qat_autotest is ran.
> 
> This is due to a duplicate call of EVP_CIPHER_CTX_free for the
> session context. Ctx is freed firstly in the bpi_cipher_ctx_init
> function and then again at the end of qat_sym_session_configure_cipher
> function.
> 
> This commit fixes this bug by removing the first instance
> of EVP_CIPHER_CTX_free, leaving just the dedicated function in
> the upper level to free the ctx.
