Subject: [PATCH] crypto: cavium/zip - fix collision with generic cra_driver_name
Date: Sat, 23 Feb 2019 00:23:23 -0800	[thread overview]
Message-ID: <20190223082323.4126-1-ebiggers@kernel.org> (raw)

From: Eric Biggers <ebiggers@google.com>

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.

Fixes: 640035a2dc55 ("crypto: zip - Add ThunderX ZIP driver core")
