security: keys: annotate implicit fall throughs
There is a plan to build the kernel with -Wimplicit-fallthrough and these places in the code produced warnings (W=1). Fix them up. This commit remove the following warnings: security/keys/request_key.c:293:7: warning: this statement may fall through [-Wimplicit-fallthrough=] security/keys/request_key.c:298:7: warning: this statement may fall through [-Wimplicit-fallthrough=] security/keys/request_key.c:307:7: warning: this statement may fall through [-Wimplicit-fallthrough=] Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: James Morris <james.morris@microsoft.com>
