Silva" Date: Mon, 29 Jul 2019 09:59:47 -0500 Subject: net/af_iucv: mark expected switch fall-throughs Mark switch cases where we are expecting to fall through. This patch fixes the following warnings: net/iucv/af_iucv.c: warning: this statement may fall through [-Wimplicit-fallthrough=]: => 537:3, 519:6, 2246:6, 510:6 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find.
