Subject: [PATCH] ASN.1: mark expected switch fall-throughs
Date: Fri, 25 Jan 2019 14:48:46 -0600	[thread overview]
Message-ID: <20190125204846.GA4106@embeddedor> (raw)

In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warnings:

lib/asn1_decoder.c:386:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
lib/asn1_decoder.c:449:6: warning: this statement may fall through [-Wimplicit-fallthrough=]

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough.
