Subject[PATCH 1/9] security: keys: Fix fall-through warnings for Clang
From
Date
From: Gustavo A. R. Silva <gustavoars@kernel.org>

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