From 0edf8593eb0985c88aa668b00befcdc1183d004d Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Fri, 12 Apr 2019 21:25:31 -0700 Subject: [PATCH] crypto: cavium - remove bogus code handling cryptd The cavium crypto driver adds 'sizeof(struct ablkcipher_request)' to its request size because "the cryptd daemon uses this memory for request_ctx information". This is incorrect and unnecessary; cryptd doesn't require wrapped algorithms to reserve extra request space. So remove this. Also remove the unneeded memset() of the tfm context to 0. It's already zeroed on allocation.
