[PATCH] audit: mark expected switch fall-through

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: kernel/auditfilter.c: In function ‘audit_krule_to_data’: kernel/auditfilter.c:668:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (krule->pflags & AUDIT_LOGINUID_LEGACY && !f->val) { ^ kernel/auditfilter.c:674:3: note: here default: ^~~~~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R.
