5.0-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 41798036430015ad45137db2d4c213cd77fd0251 ]
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.
