Subject: [PATCH] net: x25: mark expected switch fall-throughs
Date: Fri, 20 Oct 2017 12:37:52 -0500 [thread overview]
Message-ID: <20171020173752.GA10123@embeddedor.com> (raw)
In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
Signed-off-by: Gustavo A. R. Silva <garsilva@embeddedor.com>
---
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.
