From 41798036430015ad45137db2d4c213cd77fd0251 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sat, 23 Feb 2019 00:23:23 -0800 Subject: [PATCH] crypto: cavium/zip - fix collision with generic cra_driver_name The cavium/zip implementation of the deflate compression algorithm is incorrectly being registered under the generic driver name, which prevents the generic implementation from being registered with the crypto API when CONFIG_CRYPTO_DEV_CAVIUM_ZIP=y. Similarly the lzs algorithm (which does not currently have a generic implementation...) is incorrectly being registered as lzs-generic. Fix the naming collision by adding a suffix "-cavium" to the cra_driver_name of the cavium/zip algorithms.
