[PATCH] net: x25: mark expected switch fall-throughs
From: Gustavo A. R. Silva
Date: Fri Oct 20 2017 - 13:38:01 EST
In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

This code was tested by compilation only (GCC 7.2.0 was used).
Please, verify if the actual intention of the code is to fall through.
