security: mark expected switch fall-throughs and add a missing break
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: security/integrity/ima/ima_template_lib.c:85:10: warning: this statement may fall through [-Wimplicit-fallthrough=] security/integrity/ima/ima_policy.c:940:18: warning: this statement may fall through [-Wimplicit-fallthrough=] security/integrity/ima/ima_policy.c:943:7: warning: this statement may fall through [-Wimplicit-fallthrough=] security/integrity/ima/ima_policy.c:972:21: warning: this statement may fall through [-Wimplicit-fallthrough=] security/integrity/ima/ima_policy.c:974:7: warning: this statement may fall through [-Wimplicit-fallthrough=] security/smack/smack_lsm.c:3391:9: warning: this statement may fall through [-Wimplicit-fallthrough=] security/apparmor/domain.c:569:6: warning: this statement may fall through [-Wimplicit-fallthrough=] Warning level 3 was used: -Wimplicit-fallthrough=3 Also, add a missing break statement to fix the following warning: security/integrity/ima/ima_appraise.c:116:26: warning: this statement may fall through [-Wimplicit-fallthrough=] Acked-by: John Johansen <john.johansen@canonical.com> Acked-by: Casey Schaufler <casey@schaufler-ca.com> Signed-off-by: Gustavo A.
