[PATCH 075/141] crypto: ccree - Fix fall-through warnings for Clang

From: Gustavo A. R. Silva
Date: Fri Nov 20 2020 - 13:36:40 EST


In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
warnings by explicitly adding multiple break statements instead of
letting the code fall through to the next case.
